This is more then 3 months old article. You would already seen effects of it on it's price. But it is actually hard to see since the whole cryptomarket is in bearish move atm.
Anyway I think until we are down to 2-3 exchanges there is nothing to worry about.

P.S. I have seen that there is some kind of community activation on Bisq (https://bisq.network/ -decentralized exchange). They trade XMR-BTC (I think) pair there on Mondays. So if anyone is interested they can join them. I think they've made over 100k of volume one day. (https://twitter.com/bisq_network/status/1026477796883931136)
