I think what he's getting at is the initial difficulty inherent in the process of building a reputation for your personal brand or business when you don't have any preexisting reputation to leverage. There's a tough issue of gaining the momentum to make Twitter a viable marketing channel. When you're just getting started it's difficult to know who to target and where to begin. I see this bot as a relatively harmless way of getting that ball rolling. I agree with you that no one is entitled to followers, but even people with a lot of value to offer can still have a tough time getting those first followers.

Sure, I grant you that the former problem is hard. But the idea that gaming Twitter is a good way to solve it (or that solving it has anything to do with Twitter) is crazy.
