You guys should seriously think about joining some anti-coinjoin club 
So much hate towards wasabi-coinjoin and I still didn't saw a single case of coinjoin transaction being blacklisted so far!
Please let's be realistic and don't burn a witch that don't even exist...
Regarding partnership with Trezor I can't see how this could be bad for anyone, you are not forced to use this two together, and everything is open source.
I am speaking this from neutral objective position, I don't support wasabi or trezor wallet in any way.

PS
Please show me a single proof of wasabi coinjoin blacklisting case so I can join the club, or chill down a bit with this exaggeration drama.
