I've heard unreliable and whispered rumors (from the tech grapevine) that the accelerometer was a bot-farm mitigation strategy.
The idea is that a bot farm with thousands of phones on racks won't have some signature that the accelerometer should see when the screen is tapped (for example, when typing a message or hitting a like button).
I happen to believe this theory.

Recall that FB originally collected phone numbers for 2FA, but years later decided to use the information for ad targeting[1]. Not that Facebook is unique in this regard, of course; my own experience at companies which collect various bits and pieces of customer data is that, once the data is in a database somewhere, people are pretty good at finding excuses to use it.
