The developers who castigate Ubuntu are uniformly silent about the number of kernel patches coming from the Mandriva camp. They have nothing to say about how much Xandros gives back to Debian. Nobody totals up contributions from Gentoo. There are no complaints about Slackware's presence in the community. Arch Linux developers do not hear that they are not doing enough. There are no high-profile articles on how rPath is taking advantage of free software developers.
