Let me start by saying I have no idea if Facebook is reading my encrypted messages or whatever. However, I will say that in my experience, whether something is bad for business if it gets discovered is usually not a concern for large corporations, if the thing being done makes them more money. Because everything is just a balance sheet.
For an example from non-FAANG companies, see illegal dumping of toxic waste by chemical companies, such as DuPont and PFOAs [1]. Despite knowing what they did was illegal, the math works out -- products with PFOAs were something like $1 billion in annual profit, and even when they got caught the fines and legals were a fraction of that, spread out over many years.
So I personally believe these companies 100% would do shady shit if it increases their profit margins. And why wouldn't they? There is no room for morals in capitalism, and the drawbacks are slim.
