I'm not OP. I chose Garmin precisely because I don't think it's ok for corporations to have this personal data.

I chose Garmin because I can use it without needing to share any* of my data with a third party, including Garmin itself. I save the workout files to my computer via the same USB cable I use to charge the watch. There are various non-cloud apps I can use to view and analyze these workouts, if I actually cared to do so beyond the "fastest 5k" etc that the watch tracks automatically.

For this, it does not matter to me whether Garmin is bought out in the future because my watch works just fine as-is, and cannot update its OS without my explicit permission. I'm unsure what data Garmin would be capable of sharing because I have given it none.

* of course, speed/time/location data is obtained by pinging GPS/GLONASS satellites, but the watch can and does record my workouts quite accurately in non-GPS pedometer mode.
