> If the TOS changes you should be automatically opted out until you explicitly accept the new agreement

Does it not work this way? Don't the terms you sign often say something like these terms can be updated at any time? Yet they still often want you to agree to the new terms to proceed, right?

> That way if you stop using the service because of the new TOS, it actually means your old activity is still bound by the previous TOS not the new one.

Are you suggesting a statutory remedy? What is the average diff of a terms change? Are they really that meaningful? I would think the scope of what they can actually change is controlled by various other areas of law. If you don't accept the new terms are you concerned your old data is going to be used in a new way, while you remain opted out of the future? Is that actually how it works? It feels like it would not, which I gather is why they often want you to explicitly accept the new terms.

Once again it would be helpful if a specific change or event was brought up here that better explained your concerns. I feel like there are times when I am forced to agree to new terms to continue using the service, and other times where it feels like I am not. I would suspect this relates to some controlling law regarding the nature of the update itself, as not all updates are equally meaningful?
