You are suggesting Facebook doesn't mind valuable information restrictions because they have found other sets/means of valuable information.

That just doesn't follow. Facebook wants everything.

It is a near certainty that yesterday's restricted information is even more valuable today, since they can also increase its value via machine learning systems.

And high profits today don't dampen the need for growth, they accelerate the need by iteratively raising the baseline for next year. The year after. And onward. For the shareholders. For Zuckerberg.
