IMHO, Starlink is too new for what it offers, and it could only run into issues as demand intensified.
I believe Starlink will need to move to a speed-based system. Unlimited use is acceptable and most internet is now unlimited, but speed based allows Starlink to plan their infrastructure and connections better.
A 25/10 plan for most people/couples is more than they will use. 50/25 your average household will never use (parents and kids), which is a good selling point and still abundant for households.
It would not surprise me if Starlink moves to a speed-based system soon.
