Depends on the time active. If it was like the day before (2023) that pretended to be an MMO but couldn't even do that for 3 days, then yes. That should be punished. If it's your average games as a service that stays actively updated for 2 years and then shuts down I don't know if I can call that a "rug pull". That's still 2 years of actively updated entertainment, which isn't something most offline games can muster up.

I guess it comes down to how long is long enough for that 60-100 currency. I'm sure greybeards who stuck with WOW for 20 years wouldn't feel swindled if the game shut down tomorrow. Devestated, but a huge chunk of lifetime entertainment is far from a rug pull. Meanwhile you can feel betrayed by stuff like Babylon's fall that didn't even make a year (even if very few were optimistic to begin with).
