I have been evaluating IDE's from Microchip and NXP and while testing I disabled internet access on my computer and also logged any outgoing attempts.
Regardless what options I disable "no anonymous data feedback", no auto updates etc. (I believe the NXP Xpresso IDE even had a checkbox for "work offline") They ALL tried to to access the internet when started.
Particularly bad was MPLABX, it took several minutes to start because it keep trying to phone home and after running, it would try with almost every mouse click.
I currently use ST and STM32CubeMX also tries to connect on startup.
No particular point to this other than data gathering is going on with these systems no matter what the "check boxes" imply you can turn off.
