Lately it's been companies using liberal licenses to build their product up really fast and then doing a rig pull bcz "oh no we can't have competition!".
But it's also from the user perspective...
Freedom to not pay a lonely dev that's been coding on the project for "fun" or "for the community" for 15 years.
I love free software, but if y:all want it to succeed you need to support the devs!
