The biggest scam is GPL convincing people that the license will keep things open source. Every try contributing to Chrome's web engine? It started as GPL khtml, but good luck doing anything as google controls it. Meanwhile FreeBSD manages to get plenty of contributors.

Don't get me wrong, license is important. However it doesn't have nearly the effect many people claim.

KHTML was LGPL, just as with the rest of the KDE libraries. Otherwise Apple wouldn't have been able to fork it in the first place.

It is open source. You are free to fork it if you don't like the terms for contributing to that repo so long as your fork remains open source, just as Apple did with KHTML, Google did with Webkit, and Electron and Brave did with Blink. If Warp were open source to begin with, people would have been free to rip out the things they didn't like in it and build upon the things they liked, benefiting the project that was forked to begin with because they can do that as well.

Without it, chrome would be closed source entirely.
