There are quite good reasons for some hatred/grudge against MCO/crypto.com imho.
They've started as an ICO. Investors have put some nice money in there and these guys have spent a huge amount of it to buy crypto.com domain, acquisition that was seen by many a huge waste of funds (they had mona.co or something like that as website already). Of course, then the rebranding has come, which probably has costed more money.
Then they have the cards which are still not worldwide after so many years (I think that only TenX are moving slower than MCO team) and those cards were needing their MCO token in a way or another (I don't know if they do or don't do now) which was quite a show stopper for many when other card providers were giving out the cards for free and Bitcoin was enough for them.
Now MCO has some opposition and has lost some possible customers too.
PS. I've looked it up. Crypto.com domain name was bought, it seems, for about 12 million US Dollars.
