I disagree with your dismissal of windows’ security implications for companies, but to avoid mixing up concepts I’m focusing only on the end user privacy aspect.
And regulation, while worthwhile and something we should definitely be working on, is still functionally irrelevant in an environment where there’s realistically no way for anyone outside of M$ themselves to detect any violations. The plain facts are that M$ is fully capable of accessing end users’ private data without user consent or awareness (or even awareness that M$ has the data at all, in many cases). With no realistic way for them to be caught doing this, regulations or no this boils down to a matter of trust that they won’t - again, basically a pinkie promise. Sure, if they broke that promise (and you somehow managed to catch them in it) you could sue them, but again this does nothing to change the fact that they are fully capable of accessing the data.
Choosing to use windows and onedrive anyway despite knowing this, like I said before, is a valid choice as long as and only if it’s a choice that you knowingly make for yourself. It’s the wrong choice imo, especially when plenty of other services that do the same thing without the ability to access your shit exist, but as long as people are making that choice for themselves I don’t have a problem with it. Its acting like it’s unreasonable to push people to be aware of these facts and make their own informed choices is unreasonable that I disagree with.
Hypothetical for you, to test this assertion: some sicko puts a camera in a school changeroom, gets all the footage of kids they want and removes the camera before they’re caught. Privacy was violated and nobody heard it - did it make a noise?
And yes, this is very much a non-sequitur because like I said, I’m replying only to the portion of your comment I first highlighted - not weighing in on anything else, just saw incorrect info and added more context. Also, the fact that you trust them is great, but irrelevant - notice we’ve gone back to their pinky promise where you’ve just chosen to accept it (which again, valid and I’m not attacking that choice). You also seem to be conflating the personal data (literally pictures and documents) that M$ has already stolen with the more conventional data “theft” of browsing data, buying habits, etc.
This isn’t an instance of google selling your interest in some product, it’s Microsoft having access to personal files that people don’t even know have left their computer.
Another hypothetical: an innocent person with something to hide from their tyrannical government gets a windows computer, sets it up normally and migrates their data. They of course might think their own local storage on their own pc locked behind a strong password is a safe place to put whatever incriminating evidence they need to hide, so into documents it goes (and then right onto Microsoft’s servers). Now with one request from their government, Microsoft is legally obligated to hand over their data (which they conveniently have complete access to, unknown to the innocent person). Substitute the innocent person’s “crime” and the tyrannical government with whatever you prefer, and this is exactly the “practical application” of privacy you don’t believe in. Whether it’s being LGBTQ+ in parts of the world, a political dissenter in an authoritarian state, or anything else - believing that “local storage” on your own PC actually belongs to you should not be enough to get someone jailed or killed, but it (extremely) plausibly is.
Again, this is a problem not just because Microsoft has both the key and the lock to people’s data, but also because many of these people literally do not know. They’re not choosing to trust Microsoft because “nah they wouldn’t do that”, like you are - the choice has been stolen from them.
I also wanna note that you say that like it’s an unachievable goal that’s unrealistic to expect, but it’s very achievable and already reasonably common. Properly end to end encrypted cloud solutions (where the users KNOWINGLY store their files) that don’t have access to the encryption keys are out there - even Apple has one.
Interesting rephrasing of what I actually said, which was “Microsoft is capable of secretly accessing your (presumed) local stored data, with no proper oversight to actually prevent this”. I think if you reread what I said you’ll see that I stated facts (their capabilities to do these things) rather than making unprovable assertions (which would be pointless, because as previously noted there’s no way for anyone to prove or disprove that it happened). It also (in your hypothetical where it’s proven) would - according to nearly all historical precedent - lead to at worst a slap on the wrist for Microsoft. I would love to be wrong about this part, and I can only hope that someday it happens and you get to say “I told you so” lmao
