I were thinking of complexity of patching the software and keeping up with upstream (i.e. maintaining a fork). I just have a feeling (highly subjective, sorry) that some major GNU/Linux distros (especially Ubuntu) are turning from a distribution of loose coupled exchangeable components to monolithic tightly-integrated products. Well, Debian seems perfectly fine in this regard, so even as Ubuntu user (for now) I don't care much about the situation. Sorry - I were wrong writing like this was about the whole GNU/Linux ecosystem.
