Not everyone cares about the gear since it is basicly useless outside of glamour anyway. Not really helpfull that the next batch of crafted gear, which drops at the same time as the next raid tier, is better.

(This is what friends, that do complete each raid tier told me. Not a raider myself therefore I can not tell if this is 100% correct)
Your friends are right. Once you clear keeping at it is pointless unless you want said gear for glamour, enjoy getting good logs, Ultimate fight is coming or you really enjoy clearing those fights. Other players that only care about MSQ will also leave once they are done with that and come back at a later date.

As Larirawiel mentioned loosing population is totally normal.
