When I first started handling Explosives I was told Ordinance Safety Rules were written in BLOOD. Electrical Safety Rules are Written in Blood and Ashes.

So do it. Doesn't mean it's right but it's not going to burn your house down. It's not like you plai to leave it like that.
I generally stay out of the discussions about motors and plugs because I wire 5-10hp motors with 50A plugs all the time.
Yep.
Most farm grain setups use 14-50/60 up to 25HP motors, 240D 3P, rarely 208Y or 480. Never seen a pin and sleeve at a farm. Fertilizer house at the Co-Op, yes.
Everything in my shop is 6-50, nothing over 5HP, yet. I have sense enough to have breaker or disconnect off when plugging or unplugging a cord.

Yea I've seen 14-50's used for 3 phase a few times. I wasn't the most comfortable with that. 15-50 is not that much more money and it's meant for 3 phase. Eliminates possible problems.
I'll use 10-50's and 6-50's for up to 10hp single phase motors all day long though. Sure they wear out but so does every other plug

why would you use a non grounded, dual voltage plug for a 240v motor, especially when there are 6-50s?

Because they were cheap and common.

Because that's what they've used for decades. Most common use is a truck auger with electric motor.
Installing a 6-50 would mean the other dozen+ bins that have had the old outlet for 30 years would need to be changed to match. Often times they have an extension cord or two that would need new ends. It gets pretty extensive. Nobody wants to pay to change all that for a technicality.
It is a non grounding outlet but if the motor doesn't need a neutral, it doesn't, then there is really no danger in using it for ground. The only difference is the shape of the pin.
I must not be the only one. My local electrical supply stocks over twice the 10-50 recepts vs 6-50's. As a side bonus the 10-50's are 1/3 the price. Same manufacturer, same construction.
