I agree somewhat. I was having a hard time thinking of a good term, but cypherpunk was the best I could come up with (better than crypto-anarchist, crypto-utopian, hacker, geek, nerd, cryptographer, crypto-enthusiast). I did intentionally include variety even though I know it weakens the overlap. There were a bunch of things I could have included instead that would have been more similar, but I thought that was a bit boring.
The Wikipedia page for cypherpunk mentions Tor, Bitcoin, and Signal. So some of them are definitely cypherpunk. The 2 things I think are the least similar are RISC-V and homomorphic encryption. Both of those are mentioned in at least a couple threads on cpunks.org . In fact everything listed is mentioned on cpunks.org except Riot, Peertube, Dfinity, and Blockstack (although a different thing called Blockstack is mentioned). Riot is mentioned in /r/cypherpunk . There are articles linking Blockstack[1] and Dfinity[2] to cypherpunks.
I guess the only one that really stands out then is Peertube. It has a slight link due to a cypherpunk-themed instance[3] and the @cypherpunk@mastodon.social account boosting toots about Peertube.
There is one place where all those things are discussed: Hacker News. So I could have said "Hacker News user", but HN users have a reputation of being cynical, whereas I wanted a more optimistic term, and thought cypherpunk fit that.
