the main centralisation driver is that so many clients default to a small handful of standard relays. hopefully, those who use this tool are looking for *other* relays to add than the usual suspects.

one thing i will make sure to do is add a Latency column to this tool as i did for https://nrcheck.tigerville.no so people can judge which relays perform the best for them (usually a local one)
nice !
nobody should pile onto SAME set of relay FREE or PAID --- what will happen it will overload n degrade forcing users to look for other less LOADED relays --- in some way this how proofofwork POOLs used work earlier days - all miner will pile onto one BIG pool until luck turns BAD or block time is imapcted -> then people spread of once they see themselves IMPACTED eventually
However, Nostr at volume means Relays become a business, and Google Relay will be a thing. The only unknown is where the effective pricing point lies.
Yes - users can decide to pick relays - there nsa , spy, phishing n all "kind of relays" to like webservers - we r too early !!! free relays r as important as paid or private ones - like 35% web content is NOT visible to layman ordinary internet user becos -> 1. dnot need seek more 2. 80% sheep happy with what google TV shows them in search -> crawl bot doesn't crawl if dnot pay them
