(Assuming all of this is a matter of Google and Facebook not "playing fair")
I think it's very likely Facebook would still find profit in this arrangement, just less profit than before, but since they do business with other countries as well they don't want to give in. "OK we'll start playing fair and reduce profit in your market" = "OK we'll start playing fair and reduce profit in all markets"
