Is it true that in nostr,relay nodes do NOT relay events/messages to other nodes? Why are they called relay then?
Consequently, it would mean that whenni want to follow @jack I have to subscribe to at least one of his relays that he uses for writing, right?
They relay your notes to other clients
Regarding your last sentence: Most clients do this automatically, they try to find out which relays are used by the ones you follow and connect to them read-only.
This was a helpful comment. Makes it clearer to me, UI wise.
If you are interested in details try running gossip:

This client allows you to set read & write relays and you can watch on your console what it is actually doing, for example trying to determine the smallest set of relays that covers all your followees.
