For me: it's a way to access services I host on my homelab LAN from 3000 miles away. Having a router that automatically logs into that and routes TS addresses properly allows you to use all your devices connected to that router to access TS services with no further configuration. I host Kiwix, Copyparty, Llama.cpp, FreshRSS, and a bunch of other services on my homelab, and being able to access all of those remotely is convenient.
