None, zkSNACKs purchases info from blockchain companies, zkSNACKs cannot sell any info to them because Wasabi is purposely designed not to reveal any data about its users.
Hmm, sounds interesting

This is not news. We've known for a long time this is exactly what Wasabi are doing - directly funding blockchain analysis companies with the fees that you pay for coinjoining through Wasabi. Isn't it fun paying for the privilege of being spied on and censored!

You try to register an input for coinjoin, Wasabi hand that input over to Coinfirm and ask them for all the dirt they have on your input, and then decide whether or not you are allowed to spend your coins in the way that you want. If you are not allowed, they won't tell you why, of course.
Just like Satoshi envisioned! No third parties, except for ones who will censor you and charge you a fee for doing so!
