- The Hangout service is integrated only for Google Meet, with a more open domain structure likely due to Google Meet's frequent URL changes.
- Access to system CPU details is restricted to Google sites, particularly for Enterprise Hardware platform information.
- Attempts to modify commands to access hardware platform info instead of CPU info resulted in an immediate error due to restrictions.
- Chrome Enterprise PR version may be a specialized version for businesses deeply embedded in the Google workspace ecosystem.
- Chrome OS is exclusive to Google devices like school Chromebooks, with the API limited to extensions installed by Enterprise policy.
- Chrome extensions theoretically have access to system CPU calls, but the API is primarily utilized by Google for video encoding optimization.
- A Tampermonkey script was created to track Chrome API calls, revealing extensive logs from Google, YouTube, and Twitch for media-related functions.
- Concerns about privacy violations related to CPU info access by Google are mitigated by the API's limited use and lack of evidence for user identification tracking.
