Because for some silly reason meta discussion is taboo on HN. You can talk about any other site here but you can not talk about HN.
Personally I think that meta discussion should simply have a place out-of-band, instead of being suppressed.
Which of course you are supposed to ask for on the 'feature request' page where it will then be ignored...
HN is a great community but it does have its flaws (like any community), the weird thing is that there is this tendency to pretend that it is perfect by discouraging discussion of the flaws. I'm not sure I understand the background of this, but since the benefits seem to outweigh the costs I take it in stride.
Actually, I'm not too opposed to meta-discussion on HN. It does serve a purpose and I have argued in favour of it in the past.
But I do see opponents point that meta-discussion tends to get very repeating after a while and even self-serving. The latter is the reason I flagged this submission. It isn't so much the feature request, or the "when should submissions be changed" discussion, but the simple "boohoo somebody changed MY submission boohoo THEY SHOULDN'T!"
