Usually they don't. Not everyone has the skills or interest in drafting. If it's someone I know and I'm coming up on them pretty fast, I shout "Accelerate!" before I pass. That's usually on a shallow descent. Most folks will play along.

In pacelines, I like to be the rider with my wheel to the left of the wheel in front of me. So far, I've been able to steer out of a paceline accordions. I've never had a rider brake check me on purpose. That's like brake checking a semi. No good will come of it.
