I don't get you wrong but, sorry to say, with such a FUD mindset, we should no longer trust and use any private or centralized entities' products or services such as car manufacturers, public transport, connected washing machine manufacturers, ...

I have been working with Microsoft products for years and I do not see why or how they could "unsupport, or not accept our decentralized Hive". I'm pretty sure they don't even know what Hive is or they don't give a damn. Should something happen anyway, I have already analyzed alternatives, which currently do not satisfy me (for many reasons which I will not elaborate in detail here). So I'm not that unprepared.
