Instead, a Raspberry foundation approved contributor (with no affiliation with MS as far as I can tell) added a package source to make VSCode installation easier on the OS.
It's a weird approach honestly. Just include the package in your own repository instead, why update the source list... but even then, what is MS going to see? An IP address of someone that uses a Debian-based Linux distro... what's the value in logging and mining that?
It's incredibly egregious behaviour. I use Raspbian on all my pi's out of laziness because it's got batteries included and saves a bit of time over installing debian.
Perhaps the vague title? The real article is "Raspberry Pi Users Mortified As Microsoft Repository That Phones Home Is Added To Pi OS"
