Also, what's that thing about the tracking IDs? do you see that on your browsing traffic? (are you sure you're not confusing Microsoft with Google and Facebook, who track you all across the Internet?)
The information about the tracking ID's can be found here
I wouldn't say it's insecure though, it's mostly a matter of privacy.
but i would also argue that its way more secure than needed for 99% of the users
Sorry if this seems trivial, i am new to all of this
