Why do you say you can't update an otc Genisys?

Just the first link I happened across with google.
People keep saying they don't make updates for the Genisys, have been saying it since I bought mine in like 2010.
But they do make updates, they seem to lag a bit behind snap on true, but they are cheaper and you can do them yourself easily.
Unless you work for a dealership that's not usually an issue anyway, and if you work for a dealership you will have the factory scan tool anyway. So pretty much a non issue.
Now if there has been some big announcement from them saying they are discontinuing support, please direct me to it.
I'm not sure how you manage free updates for a Snap on Scanner, we just paid $1000 to have the shops Solus Ultra updated a few months ago, and while we buy a fair amount of tools from them, he never seemed inclined to give away anything other than a calendar or a soap sample.
I do think they (Snap On) quite forcing you to buy all the updates in between though, before if you waited say 3 years to update, then they wanted $3000 to bring you up to date. Now I think they just charge for the current one. Not positive on that, but I believe I read it somewhere reputable.
I seldom use my Genisys much anymore though. Few reasons for that, shop already has a scanner there, I've grown to like using the solus, its more user friendly, and I am really disappointed in the scope module I bought, its junk pretty much - expensive junk at that, so it irritates me every time I look at it.
I've never had the Solus hooked up to a Powerstroke other than for a transmission issue - us being a transmission shop, but I will make a point to check it out the next time one comes in if I have time.
I have however had my Genisys on a lot of Powerstrokes, and I can verify it works fine for that. This last weekend for example, a 6.0 no start, no sync.
One thing about Genisys is you can just buy the heavy truck module and cabling - or buy a kit with it already, with Snap on you have to buy another scanner for that.
I don't work on heavy truck so I can't speak as to how well it works one would assume acceptably, but then again I thought the same thing about the scope module.
As far as Mac vs Otc, I don't think there is really any difference except where you buy it, same machine just different colors.
