Precisely what I've been saying about open source in general for years.
There is no quality control worth speaking of, hardly any bugfixing.
When you rely solely on people doing it for the kick, you're going to accumulate a group of people who are uninterested in maintaining existing code, especially if it's code they didn't write themselves.
And when someone reports a bug he's shouted down with statements like "it's free, you get what you pay for", "just fix it and submit a patch" (never mind those get ignored if not from the core clique), "if you donate to our team you may get some time".
If there's any response at all that is, and not total silence from the developers who are basking in the light of their own glory.
