I agree theft isn't a good analogy, but there is something similar going on. I put my words out into the world as a form of sharing. I enjoy reading things others write and share freely, so I write so others might enjoy the things I write. But now the things I write and share freely are being used to put money in the bank accounts of the worst people on the planet. They are using my work in a way I don't want it to be used. It makes me not want to share anymore.
It sounds like you wanted to believe you were sharing freely while sharing conditionally.

I don't think that's the case. I'm not even arguing they aren't the worst people on the planet - might as well be. But all is see them doing is burning money all over the place.
If you want a good analogy, try the enclosure of the commons in the British countryside. Communally managed grasslands were destroyed by noblemen with massive herds of cattle overgrazing the land, kickstarting a land grab that effectively forced people to enclose or be left behind themselves. Property is a virus that destroys all other forms of allocation.

No, what you're basically describing is "I shared something but then I didn't like how it ended up being used". If you put stuff out in public for anyone to use, then find out it's used in a way you don't like, it's your right to stop sharing, but it's not "similar" to stealing beyond "I hate stealing"
