Often I see a popup to accept TOS after the update, which was run without me agreeing to anything.
At which time the company has unilaterally denied my access to something I already paid for without seeking my affirmative consent.
In theory I could stop whatever I'm doing, go email the company a brief to the point letter indicating they've broken their ToS and are unacceptably impairing my ability to use my property under the contract that I did agree to, and giving them an opportunity to amend their problem and give me a rollback path.
Realistically the outcome of this is a brushoff and needing to file a consumer protection complaint or get a lawyer.
If the feature is something like "my car" I can't afford that opportunity cost and am coerced into accepting their contract by the way they presented the amended terms.
I figure ToS for physical devices should be blanket outlawed. They're fraught enough for purely online services. Physical devices keep all of that baggage then add additional questions about whether or not I own physical objects that I purchased.
