#Facebook runs experiments that literally drain the battery of your phone on purpose to see how you change your behaviour in those situations - or how it changes the way videos and images are rendered. It calls it "negative testing".
I'm appalled that a large business can run experiments that actively harm their users for no obvious benefit, get away with it, and people still believe in the mythology of the free market that eventually ends up rewarding the best product - with users eventually picking the winners among a pool of comparable competitors.
In an ideal and balanced capitalist market with low entry barriers for competitors, a company like Meta should already have burned in a big ball of fire long ago for all of its sins. The fact that Meta is still alive, can get away with basically anything and it actively pushes away competitors (usually by purchasing them) is the most macroscopic failure of today's shape of capitalism.
