Which isn't to say that things like the 30% app store cut is entirely defensible, though you can certainly make some halfway plausible claims in that direction (based mostly on how retail works, especially at the time iPhones were invented). Or sideloading. There are legitimate gripes. But a lot of crap spewed regularly on HN turns out to be exactly that, crap.
But for some reason Apple's fans are way more insistent in defending everything and sticking to the PR department's arguments. No criticism is allowed to stand.
HN isn't perfect, but it's so much better than a lot of other online discussion forums these days.
