The point is we don’t formally know.

In China, it can be served as a salad, and I believe it is quite good.

The things I upvote and downvote are in line with my personal values and I am not ashamed of that.

Sounds an awfull lot like I have nothing to hide therefore I don’t need privacy. The goal of crypto etc is to design protocols that allow you not having to trust anyone. I don’t want to trust anyone, and I don’t.

YSK: Your Lemmy activities (e.g. downvotes) are far from private

False excuse. It is possible to design protocols that make it impossible to designed entities to see anything.
