Generator doesn't work without a Data Plan?

[brady-aiello]

The README says that Smartype is analytics API agnostic:

Smartype is designed to be used by anyone, but support today is primarily for mParticle's Events API and SDKs by way of the mParticle Smartype receiver.

But the docs say:

Smartype is designed to work with mParticle Data Plans. If you haven’t yet created a Data Plan, you’ll need to do so and download your data plan to work with Smartype.

So what's correct? I'm assuming the latter.

Running the generator is failing for me. And it makes me think I need to become an mParticle customer, and create a Data Plan if I want to run the Smartype generator. Is that correct?
