I sort of understand the logic behind that. There are a lot of people attacking Binance for how big they are, and they are rejecting to work with others because of this. Doesn't mean that they are doing anything bad, it just means they are doing what they think would be good for their company.
But the delistings were done way back, before the "attacks" started flying in. So no, they didn't delist the coins because they were being attacked.
I believe this is not the solution to their problems, they need to figure out who is the one that keeps spreading these rumours about them being in trouble and we are seeing some of their opponents in this case.
We will see when the BUSD volumes drop because of the recent developments. Paxos better fight hard and win the case against SEC because if they don't, Binance will have no choice but to probably relist the other stablecoin trading pairs.
Also, you speak like CZ is an Angel. He is the same person who attacked Coinbase without any concrete proof not so long ago only for him to delete the tweet once Brian Armstrong cleared off the claims
So if you keep attacking other platforms, what do you expect? A piece of pie in return?
