You are right though, it is a little invasive technically (not to the extent of uploading your entire hard disk and them owning it lol). But really there is nothing I do on a
computer I wouldn't do out in the public where anyone can see, so I don't care what they see. In my own personal opinion, I think there are much worse things to worry about. But that's just me and my own opinion.
I think most people focus on rather or not do they do something "bad" with their
computer. To me, that isn't the case. It's not always about rather or not someone does something bad.
We already know that they are collecting data in order to deliver ads to us. Use MS apps, use Cortena etc data mine your online AND offline searches to deliver ads custom to you. I can understand the online part. That's just an accepted risk attaching to a network (rather "you" realize it or not, rather you like it or not). Now, you can shut some of that stuff off, but not all. Given that
Windows is closed source, from a technically legal perspective, can't go poking around the source code to see what else it does with that data. I think that's the biggest thing. That not knowing what else it does.
Auto updates that you can't shut off. That I don't like at all. Numerous instances of updates having ill effects around here. But those that got the "free" upgrade get those forced upon you and only after an update has been proven to be stable, it filters down to their Enterprise customers. Some people argue the security aspect of it, well all fine and dandy until you realize some of the "stuff" that
Windows has enabled by default. Sharing "your" wifi password among contacts from Outlook, FB, and Skype. Who thought that was a good idea, much less enabled by default? I do believe that there have also been numerous reports of MS sneaking in things (changing the program name that they use for gathering telemetry (at least one of them), changing your default apps back to MS products) in those forced updates.
Win 10 is what forced me to go with VMs for
Windows (and I'm still using 7). If I have to get 10 or later, it's going to be for sure in a VM that I can isolate it's outward connectivity (which I do even with 7).
Don't get me wrong, I do like my connectivity, but I like connectivity where I have control.
