I don't blame them uniquely. I think it's a travesty the original GitHub sold out, but it's just as predictable. Giant corps will evilly make the line go up, individual regular people will have a finite amount of money for which they'll give up anything and everything.

As for how the site has become worse, plenty of others have already done a better job than I could there. Other people haven't noticed or don't care and that's ok too I guess.
