its hard to say, I need to read the last one (and maybe even more) and see what the terms of acceptance on them was. Most times by acknowlaging the terms change and in writing saying you dont agree to them and agree to stop using the things that give said terms after the change date, and even then they could try and argue 'well xyz inside your home uses this chip/IP so you didnt follow the agreed cancellation of the terms you said you would do so we own all that code' and xyz is some fucking low function thing in an auto speed fan. They are just as bad as disney with the you agreed to disney+ streaming service so dying from food allergy that you mentioned and the staff knew about and said was taken care of, means you cant sue us and must let us give you 500$ and send you on your way.
