A Microsoft file hosting and synchronization service.
Why can't you sync the account to your desktop? Once it syncs, you can disable the "back up" feature.
In other words: "Once you subscribe and pay us you can recover control over your private data we hijacked without prior notice if you will only jump through all our hoops designed without consideration for your rights or convenience but laser-focused on turning your private data into our saleable product, WE PROMISE (subject to our terms of agreement that we change at our convenience, you dumb cluck)."
Just one more tactic to deny users control over their own data.
It appears to me that Microsoft has engineered obstacles to users who wish to keep their data to their own HDDs into every aspect of MS365 function and messaging. I've at last won through your various logins and security checks and security codes that don't arrive timely to actually delete my data, and I'm offended by the difficulty at every step. Of course it's not criminal intent but MS incompetence behind my experience. Sure. You people seem to have mastered the engineering of plausible deniability and other means to foil any customers who might want to hold you accountable. And I detest the hubris with which you presume to unilaterally change the terms of OUR agreement at will.
I've never actually hated software before, but this old dog just learned a new trick.
Bill Gates is anti-human, and his products companies and employees naturally follow suit. You are "people of the lie". May all concerned get what they deserve.
Just so the point isn't missed, I am complaining bitterly. Please accept this expression of my contempt for your evident contempt for your customers.
