I’m a lawyer. I think a reasonably competently drafted terms of service could obviate most legal exposure. In the event that a promissory estoppel cause of action was established (like other posters have, I think, correctly noted, but which would also be an expensive affirmative burden to prove in court) then the plaintiff would still have to prove damages. And what is that, $10 per month per user for the affected period? And I don’t think “forever” is an enforceable affected period. So short answer, probably no practical legal remedy imho.
