If you would like a truly Global feed, go to jumble.social

Log in there and then go to settings and relays. Under "Global" add every relay that exists. Don't leave any out. No, a list of all relays doesn't really exist anywhere either, so good luck finding them all.

Then you'll need to ask all the read restricted ones to give you permission to read from them. Some of them may require you to pay for that privilege, so be ready to cough up some sats.

Now you may have something CLOSE to a Global view, if it will even load for you. Oh... except I don't think jumble will let you read from Tor-only relays... You could try all of the above on Amethyst instead, since it has built-in Tor functionality, but I know for a fact Amethyst will crash if you attempt to read from that many relays.

Welcome to true decentralization.
