The pressure needs to be put on the large public miners to set an example. I think this is the most effective way, and the best way to do this is not via nostr, but via twitter and news sites where the readership and engagement is still much larger. Marathon copped a lot of flak on Twitter when they began mining only OFAC compliant blocks, and they quickly changed. https://www.google.com/amp/s/www.theblock.co/amp/linked/106865/marathon-ofac-bitcoin-mining-pool-taproot I have requested on multiple occasions comment from Riot Platforms and Pierre Rochard regarding their stance on mining pool centralisation but am yet to receive a response. I don't know if that's because they don't see it as an issue, or they are just trying to to protect their profits, but in my opinion it's not a good luck for a company that many look to for leadership in the industry.
