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.)
