alt Hacker NewsPeople are paying money for Ubuntu, though. I suppose if only the free versions were unpatched we could consider the ethics and merits of who is allowed to complain about what, but when the paying customers are also being left out in the cold I don't think your argument has much merit.
Sure, and those people have a right to complain.
But, imagine if the complaint vs paid ratio were more equal.
Right now, the ratio is massively skewed towards complainers vs paid. (>99.9% I'd guess)
