I’m not sure I can answer that in detail. Also, “safe” is kind of vague so I’m not sure what your threat model is.
But I will say that I would 100% be running it as my home windows if I wasn’t using Linux. Do I think it’s the equivalent? No. Do I think there’s a possibility of Microsoft turning things back on with updates? Yes. But its far easier than running O&O and a bunch of power shell scripts to try to remove bloat and telemetry hoping you got everything. I have no complaints.
Exactly. I tired SuSE back around 2001 and Ubuntu around 2006. It was not a better experience so I never stuck with them. I started using Mint last year and it just stuck. There are some quirks and learning curves, but it’s a good experience. Linux has changed a crap ton.
