This is the smartwatch I own. True netrunners know that the tech we wear on (or under) our skin is a prime entry vector for ever hungry megacorps to bleed the pulsing data from our digital veins, so having a wearable I have full control over is of paramount importance. I can flash it with new firmware whenever I want, the multiple open source options available are all an open book to any hacker worth their cyberlinguistic salt, and I can know for a fact that it won’t phone home with my location or other data to any corporation behind the scenes. If we are all going to be cyborgs integrating technology onto and eventually into our bodies, better to control that tech ourselves!
The problem is that that’s mostly marketing smoke and mirrors. They define privacy as not giving your data to third parties (who aren’t subcontracted with them), not actually refusing to collect in-depth data or link it to your personal identity. There have been a number of pieces of evidence released recently that show that they actually collect as much if not more data about you then Google does, and tend to ignore your privacy settings.
Depending on your phone, you could use GrapheneOS (which is super easy to set up compared to rooting and basically the best security and privacy you can get in any smartphone) or CalyxOS. Both easier (and more effective) than rooting, and certainly better than Apple.
