How do you know which code Wasabi is running on their servers, though?
I don't know, but how do you know which code is running on any servers for all other bitcoin wallets and services you use?
I use my own node, that's it...
Either by connecting SPV wallets to the
electrs instance running on it or using it directly.
I am not defending wasabi or anything else, but someone running closed source wallet knows even less.
Why are we talking about closed source wallets? The Trezor is open source - hardware and software.
Sure, I am not trusting wasabi very much with their new coinjoin, but I wont trashtalk them without any proof... if someone want's to be speculation king...go for it

What do you consider as proof?
For me, their word is proof enough.

speculating here is someone else.
