After GCHQ was discovered doing this back in 2014 with their 'Optic Nerve' program[0], I have tried to avoid computers with integrated webcams for use as my personal devices (exceptions are mobile devices).

An exception to that rule is if they have hardware switches for turning off the power supply to the camera and microphone.

Currently, I am very happy with my Framework, where the LED is hardwired into the power supplied to the camera[1].
