From what I've seen, though, most of the people who would be fine seeing content removed are also not too invested in the game to begin with. Their priority tends to be glamour and potentially the MSQ stuff as well but beyond a few exceptions they don't tend to invest in side content such as BLU, high end raiding, PvP, Beast Tribe daily quests and so on.

So they'd be perfectly fine with such content being delayed/removed because they have no investment in it. I'm not saying it's wrong to invest only in one or two aspects of the game. I'm just pointing out that the concerns of removing content are downplayed at times by those who don't have any ties to it in the first place.
