I can understand not wanting to be associated with the billions of tinycoin ICO scams or NFTs that are just URL links or whatever else.
But to reject things like Bitcoin or Ethereum seems to me to be a denial of reality. Just because it's not useful for you, doesn't make it not useful.
For clarity, I will be affected by this change and I don't at all believe my code is socially negative, but I'm not interested in justifying myself. My favourite ice cream flavour is not yours.
In the end, Git is decentralized and running cgit or whatever is pretty simple stuff. I just had high hopes for sourcehut.
On a long enough timescale I suppose anyone lets you down.
