If I was the pool owner, I wouldn't care either. Size is close to unmanageable, why would I care if a few complainers left? Won't hurt the bottom line of the pool at all (check growth graphs, it only goes up). So that's why he doesn't bother to answer... there's no reason to!
Exactly this. Its the ancient human issue of "I wish i had thought of that first". Same with the whole crytpo scene really. Full of the jealous type who wish they had done something first or this or that etc. This pool works on a scale far larger than another pool you could find and that alone is impressive enough because i would like to see anyone complaining be able to even create a pool like this, let alone mantain, expand and reply to every nay sayer.
