Given that many (most?) bootcamps are for-profit, it stands to reason that they should be able to pay for a basic level of Heroku services that their students can use, no?

You're acting like they're dead, but that seems quite a bit premature.
Let's remember that the purpose of a free tier isn't just to give free stuff away. It's a marketing expense. The hope is that you get people to use the platform without the huge amount of friction involved in pulling out a credit card, and hope that they not only stay, but require more services that push them out of the free tier. You also hope that these free users will tell their friends and colleagues, who might also become paid users.
I'd guess that many bootcamp users would just use Heroku for their class projects, and after the bootcamp was over, never use it again. Their projects would just sit there, deployed on Heroku, active, without being used. Sure, some would end up using Heroku at whatever job they end up at; but, critically, most of them will be going into an org where it's already in use, so the free tier would not have acted as a customer acquisition tool in that case. And sure, some much fewer number would continue using Heroku in a capacity where they wouldn't otherwise do so. And finally, sure, some even much fewer number would both continue to use it, and start paying for it.
I'm sure Heroku's new-customer funnel will suffer somewhat without a free tier. But presumably they believe it's better for them not to have all that fraud and garbage on their platform. And they've been around long enough that they don't really need to work on increasing mindshare all that much.
