> You could split off the ad selling wing from the rest of it for a start. Normally when businesses are split up, they are broken into multiple pieces that each have their own revenue and are viable standalone businesses. In this case, the ad-selling part of Facebook is the entire business as far as financials are concerned. It's the only material source of revenue for Facebook. If you were to split the ad-selling wing from Facebook, then the "remaining part" would have no revenue. A regulator action along these lines is tantamount to crippling or shutting down the business. Source: Facebook Q3 2018 earnings show that the only material revenue is advertising at $13.5 billion (Q3 2018): https://investor.fb.com/investor-events/event-details/2018/Facebook-Q3-2018-Earnings/default.aspx https://investor.fb.com/investor-events/event-details/2018/F...
