What is not understandable here? Crypto is all about decentralization, Community Notes embodies that value (obviously not ideally, because Twitter still can decide to do whatever).
Community Notes is “decentralized” only in the sense that it’s derived from the collective action of multiple users. Do Hacker News scores embody the values of crypto? If not, why not? Because Community Notes uses more complicated math for its weighting system? How can we make that claim and not end up going back to the early days of Slashdot and declaring its user-driven moderation system to embody the values of crypto? Oh my god, was Commander Taco Satoshi all along?
Community Notes is an interesting example of collective moderation, but it’s an example of collective moderation, a long-standing thing that has nothing to do with decentralization as I think most people understand the term. The objection here, I think, isn’t to Vitalik’s interest in it — it’s to the “if all you have is a cryptocoin, everything looks a blockchain” mindset.
If “crypto values” literally just means “decentralisation” then just say decentralisation. It’s weird to invoke something that adds absolutely nothing to the comparison (unless, say, you’re trying to hype it up)
