I keep covering them up with bits of paper (because like most people, I don't trust LEDs or switches) that look ugly and invariably get blown off by a gust of wind and have to be reapplied when moving.
It just seems like at some point around 2010 some cabal decided that every device with a screen needs to have a camera facing the user and a microphone.
The whole point of a laptop is to be able to move around and travel with it.
FWIW you can still encounter laptops without webcams (MNT reform comes to my mind) and you can also choose to disable/load/unload the kernel modules for them dynamically on linux distros and BSDs
