If you care about actual functionality (accurate HR, fitness tracking, GPS tracking for runs) but still don’t want to be spied on, using GadgetBridge with a commercially available watch (Huawei/Garmin/Amazfit) is probably your best option. GadgetBridge being the controller/gatekeeper app to the watch means all your data stays on your device and isn’t going to the watch manufacturer, but you still get the benefit of the actual functionality working well (which, unfortunately with Pebble or PineTime isn’t the case right now - pebble being very old iirc and pine time just… Not being good.)

This isn’t awful advice, but used Pixel prices are vastly out of whack with used prices from just about any other android manufacturer. On Amazon I can currently buy a refurbished Galaxy S25+ for $300 less than a refurbished Pixel 9 Pro XL - when the Pixel is a worse phone by every metric but its ability to run GOS.

Also, in some markets (US I believe? I think its a company called Verizon that does this) Some pixels just cannot be OEM unlocked, at all. So that’s also a risk buying used online at least - there’s usually not a way to tell if you’d be getting one of those if you live in a market that has this fucked up “feature”.
