This is why I really try to buy devices that can run Tasmota. Any Tuya compatible device can be flashed to work with Tasmota. I have actually left some devices with the Tuya firmware on there - their app is pretty decent. But I know if I need to I can flash Tasmota and make it appear on my network like a legacy Phillips Hue or Belkin Wemo device that doesn't require an account.
Buying hardware that can run open firmware is nice for future proofing in case the vendor goes sideways with their firmware. I do the same for routers with OpenWRT.
