Sounds like a skill issue tbh. I’ve never run into one drive trying to grab up my entire documents folder, across 4 separate windows computers and multiple installs. And I doubt Microsoft has just decided to bless me, personally, in this regard.
A lot of total asset replacement mods and ports require some form of check against a legitimate copy, such that they aren’t distributing copies of a game, just a way for people to modify their own copy. It isn’t a flawless legal defense, far from it, but it’s a whole lot better than just getting hit with “you’re just outright distributing a copy of someone else’s game”
I just find this specific complaint to be absolutely perplexing because not only has one drive never just started syncing random stuff, I have to make sure the things I put in actually get synced and aren’t just lest waiting when I close the system. And this is on factory installed windows where I’ve largely not messed with anything.
