Why large companies fail - they put revenue ahead of customers.

How long a company can get away with that depends on their moats, competitive landscape, and what alternatives exist. In the case of FB, obviously there's a huge moat and a semi monopoly.

There is some competition from Twitter and Snapchat, but really FB acquiring Instagram doubled their market cap, because that is the only other social platform that has truly reached their scale, and also has an effective, if not more effective, ad platform.

This is also pretty typical even at smaller companies. Different people have different "masters". The product manager is rightfully trying to build the best product for their customers - the advertisers. But the upper management has bonuses tied to revenue usually through stock compensation, so their interest is in their own pockets. The product manager who correctly points out a real issue, is then seen as a negative, rather than someone doing a fantastic job.
