It's easy as a developer to slip into a role where you want to build/package (maybe sell) some software product with minimal obligations. BSD-likes are obviously great there.
But the GPL follows a different perspective: It tries to make sure that every user of any software product is always capable of tinkering and changing it himself, and the more permissive licenses do not help there because they don't prevent (or even discourage!) companies from just selling you stripped and obfuscated binary blobs that put you fully at the vendors mercy.
I'm of the opinion that what I build, I'm willing to share it and let others use it as they see fit even if it's not to my advantage.
My view is that every project and library where I can peruse the source is a gift/privilege. GPL restrictions I view as a small price to "pay it forward", and to keep that privilege for all wherever possible.
So ultimately while good intentioned, you end up limiting how many people can use what you've built.
GPL: Help the user
MIT: Help some random company screw the users and save money not hiring people.
Then again I see you're a founder at some AI company so I strongly doubt your motives and statement.
Are you complaining about proprietary software? I hear the restrictions are a lot tighter for Photoshop's source code, or iOS's, but for some reason you are one of the people who hate GPL as a hobby. Please don't show up whining about "spirits" when Amazon puts you out of business.
