I'm pretty surprised they haven't just Maliciously Complied by offering an in-app signup buried somewhere obscure in the app, with lots of big flashing warning signs saying "don't click this, it's only for compliance reasons" - and a nice discoverable easily-followable link to the browser-based sign-up.
They could be continuing to make the (justified and correct!) stink about Apple's terrible practices, while also having their app on the store (or forcing Apple to further highlight how arbitrarily-applied their standards are). Win-win.
