I don't think you get the point between sending KYC information to a regulated finance platform and anonymous platform. They are not the same. CEX asking KYC is worse, but anonymous asking KYC is much more worst.
You are right but your post recalls one hilarious project, Brave browser.
Years ago, they prided to be a browser for privacy but later they ask their users to complete KYC of wanting to claim BRAVE token. It is funny and I did not do it to get their token.
