Festool did that on purpose with the Ergo batteries, because they are offering a mains adapter for those small sanders utilizing said Ergo batteries. Whether that in itself was smart or not, I won’t comment on. What was smart, realizing that without a mechanical lock-out, people would use the mains adapter on all the other tools, with catastrophic results. Ergo batteries are still compatible with the same chargers their regular 18V batteries use. So the only inconvenience is that Ergo batteries only work with the sanders they were designed for. And if you made the decision to buy these, you knew that.
As far as I know, Festool was supposed to be a part of Ampshare when it launched, but pulled out in the last minute. At least that is what I have been told by people who saw pages of the presentation pre-release/ announcement. Whether that is true or not, I don’t know - I couldn’t prove it one way or the other. And let’s not forget the whole TTS/Festool/SawStop vs. Bosch Reaxx saga …
Festool is now trying something “interesting”, sourcing tools in China/ via Chervon to cut engineering cost/ time on releasing non-core-competency battery powered tools. How smart that is, only time will tell, and it’s another topic I won’t comment on. And with that move, they still kind of doubled down on keeping their own battery platforms alive for the foreseeable future.
Metabo still has a few unique tools that stand out, this one for example:

Personally I’ve encountered Metabo as a brand wearing their noses so high, they could scratch them on the pole of the Empire State Building.
Given what I see at suppliers and retailers, I give them a couple more years before they go the way of the Dodo. At least as a tool manufacturer. Maybe they can sustain as a CAS battery/ powertrain supplier, one way or another.
Bosch (Professional/ blue for those that actually can buy both lines in their country) is now proudly playing the “Battery of the month club” game and has at least released a couple of tools that were asked for, for a long time and the Milwaukee gang has had for years. They are also venturing into hand tools, electrical testers/multimeters trying to please the “we need everything blue” crowd.
From what I read, Bosch - and I’m talking the mother of all motherships - is sailing in troubled waters as well. And not a horse I’d bet on right now.
This post states my personal opinion, and only that.

The sanders weren’t the first time Festool had proprietary batteries for particular tool models.
Back during the NiCd days, Festool, (at the time Festo), had two cordless drill models, the CDD and TDD that were both 12v drills, but which used completely different batteries, with the CDD model using an “L” shaped battery, and the TDD drill using a standard rectangular block, although with the top stem design some older batteries used.
In Europe, there was also a 9.6v version of the CDD drill.
In Europe, the fast “12 minute” charger that was used for the CDD charger was a dual purpose charger, that had separate charging bays to charge the CDD battery, and the TDD batteries, since the batteries had different charging/connector designs.
This charger design left potentially live connectors exposed, so the original chargers were modified for the US market, removing the TDD charging bay, therefore requiring different chargers for the contemporarily made CDD batteries, and TDD batteries.
For the European market, NiMH batteries were also offered, which were never offered in the USA.
The weird CDD battery type was for ergonomic reasons, since the drive system actually had the motor mounted in the handle, perpendicular to the chuck axis, with the drive passing thru a right angle drive, to the gearbox, before hitting the centrotec arbor.
On later models of the drill, Festool was able to switch to a more compact motor, which then eliminated the need for the right angle drive since the new motor was compact enough to keep the same overall head length and Festool simply switched to using a slide in brick battery, of a style similar to what is used nowadays.
Festool made multiple drill voltages though.
The new chargers would not work with the old batteries though, and the old batteries would not work with the new chargers, and Festool didn’t make battery adapters.
I think Festool then switched to standard 18v lithium battery system, which may not have been comparable with most of the older lower voltage NiCD batteries, and again, with the older chargers also not compatible.
Festool then made some other tools using these same batteries, implying there might actually be dome sort of battery system approach.
Then Festool came out with the sanders, using proprietary batteries, which then basically ignored the idea of a “modular” system for their cordless tools.
As for the Festool sanders, I presume they were made to compete with some specific sander, (I recall one in particular, but can’t find it at the moment), that had exceptional ergonomics, since most power tool manufacturers (Makita, Bosch, etc.), just use the normal brand brick batteries on their cordless sanders.
As for Chervon manufacturing tools for Festool, that is likely a legacy arrangement, based on the fact that FLEX, an originally German tool brand going back almost 100 years, used to manufacture tools for Festool, sometimes with modifications on a tool sold under the FLEX brand, and Chervon bought FLEX, leaving Festool to find a new supplier, or have some tools made by Chervon, in China now since Chervon seems to have shut down the German production facilities.
The Festool PS1 jigsaw for instance was made by FLEX, but with the addition of the lateral blade guides Festool is known for. Festool may have taken over production of some of the later models.
Some of the Festool sanders might have been made by FLEX.
I forget what else.
The reciprocating saws are likely coming from FLEX, and now Chervon, because FLEX specialized in reciprocating saws, which they made for other brands such as Fein, Metabo, and for Ridgid Europe for sale under the Ridgid brand. (The professional pipe tools brand).
Incidentally, “back in the day” it used to be common for power tool manufacturers to make adapters do that the slide on batteries that started to become common, could be used on older tools people had purchased when the older battery systems got discontinued.
