The last part isn't meant to chastise you. Twitter's API has long been free to access so it wasn't unreasonable to assume it would be so. But it has been true pretty much forever that you should not rely on someone else's goodwill and charity for a critical part of your project or business.
(None of this is to say that this change isn't being badly managed, just that I think you still have options here, despite being somewhat unpleasant.)

As a parent of a kid with ADHD and a Chromebook, I'm appalled at how wide open access to everything on the Internet is on Chromebooks. Trying to keep him on track when there's the constant temptation and ability to alt-tab over to YouTube means my wife and I have to be ever vigilant that he's actually working.
No, his ADHD isn't Google's fault, but they're designing and deploying tools for lots of kids who have impulse control issues.
Edit: It's not just the US (!) Maybe a 'North American rail network map'?
