A lot of shit Facebook is doing is another factor for leaving. Leaked documents admitting to political meddling (more or less), enabling the far right, not targeting hate speech etc. Facebook was even blatantly complicit in literal genocide in Myanmar. All for profit.
There's typical greasy tactics that you'd expect - the evil shit Facebook is part of is an order of magnitude worse than that. I happily pick and choose my battles, even see things as being necessary evils at times at the point of hypocrisy, but I can't be part of that website any longer.
