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).
I do... I consider it the opposite of freedom. I think it places severe restrictions on your project that make it hard/impossible for some people (like companies) to use, especially if your project contains lots of code from other people that make it really hard/impossible to try to re-license if one day you decide you like/need money (assuming you have no CLA, I don't like those either).
But I also realize there's different kinds of freedom... freedom TO vs freedom FROM.
Some want the freedom TO do whatever they want... and others want freedom FROM the crazy people doing whatever they want.
I wish there was a happy medium but centrism doesn't seem to be very popular these days.
I agree that you can't legally take a bunch of GPL code and relicense it as proprietary. That's the point.
Freedom to/from is a false dichotomy; most rights can be expressed equivalently in either "to" or "from" form.
No, MIT is a donation of your labor to the public. That includes corporations, yes, but it is not only corporations.
