Hey! You don’t *need* to remove other relays but if you’d like you CAN remove the ones on our read/broadcast list and you’ll have the same content with less latency and duplicates.
Depending on your client, you can also limit which relays you are reading from in which views. For example, Damus let’s you choose which relays you want to read “universe” from. Amethyst let’s you control relays in each view. Snort let’s you choose one relay at a time to browse in global. Lots of options!
