@jwildeboer @pravee_n my understanding was that anyone *could* run a relay, but even their docs admit it’s a ton of bandwidth and implies there’s not much incentive to do so. So maybe they are practically running all the relays and that makes them practically centralized.
Still, it seems to solve for the problem of the Mastodon effect where sites are getting DOS’d by instances requesting data for thumbnails.
Personally, I see pros and cons. To each their own, though.
