Ownership is a social construct. The leviathan can come and take away your bits at any time.
Licenses are meaningless, period.
{L,}GPLv{2,3} has corporate lawyers consistently shitting themselves. I derive meaning from this.
Then I hate to break it to you but that’s totally not true. It might have PMs or engineers shitting themselves, but the lawyers don’t really care. It’s just not a big deal.
They play that game because they have to. Your average Joe is not going to be sued for ignoring a license.
