Sorry, "fork" was the wrong term. How about "long-term working branch that might get merged eventually, but also might get used in preference to the original to the point that people start just submitting their PRs directly to it"? (Think egcs's "fork" of gcc.)
And by "Not everybody" you of course mean "People who don't know any better", right? The Qt legal situation has changed a lot lately, especially since Nokia went out of the picture. Look it up:
The situation is that a CLA is still required.
Personally, I don't care (I'm just a consumer who is not affected by the CLA). Others care and insulting them as "People who don't know any better" is not right.
WTF is it with people's first instinct being "let's fork instead of contributing fixes"?
