GPL is unpopular, and if you want people to use your software, it is the wrong license to choose.
Should it be? Perhaps not. ...but I don't think the parent comment is nearly as wrong as people seem to think.
It doesn't matter if the GPL technically is a better or worse license; the fact is that (perhaps indeed driven by large corporations) GPL has a very negative image right now, and since we do live in a 'look at my popular github repo with oh so many stars, aren't I popular, oh btw hire me pls' world now, that is actually a big deal.
The question is not, 'should I use GPL?', because the answer is no, if you want to have a successful popular open source project.
The question is; how do we actually change the perception of GPL so the answer becomes yes?
I'm not sure... but I think it's a far more important question.
(I can certainly say that I no longer use the GPL, after using it for many years, largely because it was requested I remove it from projects. What do you do in that situation? Since I really don't care that much why not just put it under something else? I don't have a good answer.)
