I have a network-wide pi hole and I noticed that it requested activity.windows.com, a url blocked by my pi hole, even while my pc is suspended. I pinged 10.0.0.217 and it is currently unreachable. So, somehow, windows pc’s turn on networking, phones home, and turns off even while suspended.

Can Teams not be run inside Chrome as an addon, preventing this disk space nonsense?
I guess so - I’ve actually never used Teams. There are lots of potential mitigations, but sandboxing is not really a solution to buggy code. For some better engineering discussion on the topic, there’s the series of articles Transparent Telemetry, in particular The Design of Transparent Telemetry.
There actually exist a couple options on Linux, Snap and Flatpak versions of Chrome based browsers. Both of them are sandboxed forms of software packaging.
