Understanding The Inner Workings of the F-Doid ApK

I am struggling to decipher the information provided on scanners for the F-Droid APK. My intention is to A). Determine that my download is indeed the original file as intended by F-Droid, and B). Interpreting the connections, behaviors and dev mysteries more each day.
Please help me learn so I can join into the discussion more intelligently.

My first hurdle is this:

  1. Why does my scanner indicate that there is such a heavy presence of windows activity in the APk?
  2. Why is Google being communicated with so much by the apk?

Windows? What do you mean? Example?

It’s not, maybe your scanner is faulty, or maybe it’s an emulator with a full Android system that has Google Services and those connect to Google.
