Indeed. If you use Chrome, you should just assume that your location is shared with Google at all times, since they likely collect it via telemetry anyway. If you use Firefox, assume your location is always shared with Mozilla via telemetry... and likely indirectly to Google as well, since they use Google Analytics for so much of their infra. Likewise for Apple/Google/Microsoft collecting data from iOS/macOS/Android/Windows. And of course your cellular provider. As far as I know the only way to ensure your personal data isn't shared with your browser publisher is to use a verifiable, open source browser that has telemetry disabled, like Iceweasel or Librewolf. And an open source, verifiable OS with telemetry disabled, like... Fedora, maybe? Manjaro? But you're being spied on by your ISP or cellular provider anyway, and the US government indirectly through your ISP and cell provider. And let's be honest, foreign governments through some combination of ISP/cellular provider/govt backdoors. Oh, and if you've read "Trusting Trust" you'll know that even OSS isn't necessarily verifiable unless you wrote the compiler yourself from scratch. So I'm not sure there's much benefit to any of it?
