I'm not sure there's any "decentralized" exchange for XMR.
Bisq is the best option.
But when you've said about it gaining lots of adoptions from exchanges, you have to consider the news of it being delisted mostly in popular exchanges and I think in some other global exchanges as well.
As far as I see it, being delisted from KYCed centralized exchanges is a good thing - it proves that Monero works, the government are unable to trace it or deanonymize it like they can do with every other coin, so instead they are resorting to delisting it. Delisting shows that it works. And as I said before, no one who actually uses Monero cares about this since they aren't using KYCed exchanges in the first place.
There's a big issue on it and as we can see, it's being cracked by the governments.
So is bitcoin. We are seeing mining pools censoring transactions the government tells them to. We are seeing wallets like Wasabi censoring inputs the government tells them to. We are seeing regulations which will ban self custody and mean bitcoin can only be bought, stored, and sold on fully KYCed centralized exchanges. And yet no one seems to care that bitcoin is marching towards a government permissioned network. Bitcoin is being cracked down on by governments even more strongly than Monero is. The difference is they can't do any of these things with Monero, so they are just forcing it to be delisted instead.
