The problem with GPL was "tainting." It was never clear in what cases you could use GPL without it dragging all your code into being freely available. LGPL was supposed to help with that; AGPL made it even worse. The lawyers were terribly confused and recommended you just not use anything with "GPL" in the license.

The reason why MIT/BSD licenses flourished is that they were easy to understand. As long as you didn't sue the original author or try to claim the code was written by you, you were free to do almost anything with it, including mixing it in with other for-profit code.

Whether that's an abomination or a blessing depends on your corporate vs. free software politics.
