This is a long discussion now, and answering everything point by point will be a lengthy exercise.
I’ll say this: I believe in a world run by corporate interests, piracy is similar to civil disobedience. If we collectively decide to create friction to the functioning of the system, it can in combination with other ways of resistance influence the situation in our favour.
I would assume Bosch knows how blatant paywalling features looks and will backfire just like it did for BMW.
I am guessing Bosch wants to create a Bosch ecosystem where you can control all your home appliances with a single app. This is what PC OEMs did with RGB software. It’s not really for surveillance although they do use it to push ads/premium features. The main intent is to lock you into their ecosystem and then you only buy products from them. Samsung & Apple do this are well known for this, and that’s what they’re emulating.
