I'm not trying to defend them, I'm more curious what your definition of anonymous would be? Eg, they could say anonymous and not store any data either, but potentially you can still be identified through an oversight - meaning even if they attempt to be anonymous, you might still not be anonymous. If taken far enough, only the most rigid, hardened and secured communication seems well vetted to keep you anonymous - but then we can't even trust them running it either.

So yea, I'm just curious what's reasonable here. What would make you feel good when associated with the word anonymous?
