the penalty is just peanuts for them and I believe they are not fully remitting all their collections or income, so their net worth is not really the real one, it's lower than their real net worth.
The government were able to make on facebook violation but they should not impose the same light penalty in the event they will repeat their violation again, that would be very corrupt of the government if they still do the same, they have to serve the people, not the facebook.
You call that peanut; let them continue to pay that peanut every year and then see if they will not go bankruptcy. Pay attention to what the op said, he never quoted the amount in million, we are talking off billions of dollars here my friend and you call that peanut? That is not peanut man.
I am sure this is one of the reason why they are also planning to use blockchain technology for their project too, and Facebook is very wise, they are making everything concerning them decentralized but they are not making the coin itself decentralized, which means, they are just doing this to really get back at the government and government better tackle them right now, before their Libra coin takes over globally and even get recognized more than the United State usd.
