>Facebook earned about $172 billion since 2013. Do you think facebook would have earned $167 billion while behaving legally?

>5 billion is ... an order of the magnitude off

So you're saying a 30% of their income came as the result of illegal activity? That's a pretty strong statement to make. What proof do you have of that?

Do you want to punish Facebook for doing things that are legal (but arguably not ethical) or do you want to punish them for doing things that are illegal? The former means you're essentially advocating for an ex post facto law and it's easy to understand why some people would see that as not fair.
