There is really no need to figure this out, because Paxful doesn't mean big enough that we should care about it. ETH would not be hurt by Paxful doing anything, not only delisting but they could come out and bash ETH constantly once a day and it would still not matter.
It just means that there is someone there who dislikes ETH and they just wanted to remove it for personal opinion reasons, but that is all there is nothing else to it. ETH is one of the best coins out there, second highest ranked coin of all time and we are talking about a situation where it is not going to be as easy as people make it out to be for ETH to go down a lot more.
I am in solidarity with you! To be honest, I don't even know who it is, but it seems to me that for the Ethereum platform it is more advertising than anti-advertising, since you correctly indicated that this is the second coin in the rating and therefore there is some other incomprehensible reason why they decided to remove Ethereum from the exchange.
