As outlined by Arizona news site WGEM, under the Freedom to Describe Directly Act, distribution platforms like the App Store and Google Play would not be able to force Illinois developers to use a “particular in-application payment system” as the exclusive mode for accepting payments, nor would they be able to retaliate against developers who opt to use an alternate payment option.

And:

North Dakota, Arizona, and Minnesota have all attempted to get around in-app purchase rules by passing bills, but Apple and Google lobbied hard against them.

And:

Apple’s chief compliance officer Kyle Andeer said that Arizona’s bill was a “government mandate that Apple give away the ‌App Store‌,” and Apple’s Chief Privacy Engineer Erik Neuenschwander said that the North Dakota’s bill threatened to “destroy the iPhone as you know it.”

As Apple’s Kyle Andeer implied, all it takes is one of these bills to pass to change everything. After all, how could Apple prevent someone in Illinois (or any specific locale) from breaking such a law? And no developer is going to want to have to write code that runs one way in Illinois, another everywhere else.
