Wonder how a court would treat it if users just reply to the email updating the terms of service on our behalf and claiming that they have accepted the terms by not doing anything. (Eg add stringent PII protection, no tracking requirements…)
My guess is that you would probably get kicked off the service if anyone reads your TOS, so make sure to add onerous cancellation charges due to the user in your updated TOS.
In the US at least, the courts would probably side with the big corporation, since doing so seems to be the legal precedent.
I could imagine an AI sidekick that does all this work for you, and always has the last word because it'll never give up.
A place like Meta or Microsoft would tell you to pound sand, but an aligned army of collective-bargaining agents might succeed in removing a specific term from a smaller service.
