This is an oversimplification. I'm sure that some people think like you mention, but it is by no means all. I personally choose permissive licenses because I find the GPL to be hypocritical in the way it restricts freedom while talking about promoting freedom. If I'm giving a gift to the commons, then I want it to be a true gift, not something with strings attached. So for me, permissive licenses are the way to go. It hurts nobody if someone chooses to make a closed source fork - software is a non-rivalrous good, so whatever someone else does cannot take away the free version that I have provided. So I see no reason to deny others the freedom to use my software as they see fit, even if they use it in ways I don't personally agree with.
