No, MIT is a donation of your labor to the public. That includes corporations, yes, but it is not only corporations.
If you didn't want to give it to everyone, you shouldn't have chosen that license.
And if you choose a non-commercial license, people get upset that it's "not technically open source because the OSI says so" as if they are somehow the arbiter of this (or even should be). It's not like anyone owns the trademark to the term "open source" for software either.
Ironically, I've seen a lot of people in the last several years quit open source entirely and/or switch to closed source.
A lot of people have been taught `corporations == bad`, part of the anti-capitalism efforts taught to our youth for a couple generations.
To me this is just like getting upset when someone forks your open source project. Which ironically I've seen happen a LOT. Sometimes the original developer/team even quits when that happens.
It's like... they don't actually want it to be open source, they want to be the ONLY source.
... but MIT is what corporations told them they want. There has been a low-level but persistent campaign against xGPL in the past several years and the complaints always trace back to "the corporation I work for doesn't like xGPL." No individual free software developer has a problem with xGPL (SSPL not included).
Bernard shaw put it best:
If at age 20 you are not a Communist then you have no heart. If at age 30 you are not a Capitalist then you have no brains.
