I love what nostr:npub1dd9znw7585wsam4d8p84ztdmtywwjsrayld6fzk4fvqdn5hpju4st5xe7p is doing, but on iOS it doesn't work when nostr:npub1wr5azetlyy80apyxfp6y3eky3j54g0typwh3ceuftwvur4dmqjesqcjeva is used. Is using the paid nostr:npub168euw93e4cam59llcmydav0akwjk2p4nfy3p85pn22xv9y2jxuzq4s9uaw exit node service directly in Tailscale an adequate alternative, or are there any downsides?
