OK, but that’s not what the thread is about. The thread is about the OP arguing that end users shifting away from Windows is not a solution because companies and other users who interact with them are using Windows and that’s a vector that will compromise their data.

Which is not really a thing, as far as I can tell.

Also, no, it’s not “pinkie promise”, their data protection obligations are regulated (differently depending on where you are, but they are) and even in scenarios where you’re solely relying on their terms of service they may be liable if they are negligent about it. I don’t trust MS. I don’t trust any company. I do business with them and if they bone me as a partner or a customer I have whatever recourse my government’s regulations grant me.

I don’t need to be a digital prepper with every single picture of my dog secured by my own hand, personally. And even if I chose to be that guy, as the OP says, it’s a systemic problem. I shouldn’t have to rely on my own tech skills to secure my information, this should be a regulated space where normal people don’t need full end-to-end control to be kept reasonably safe. Yes, even when using Windows, or Android or whatever other service corporations are providing to them.
