>> They fear being replaced/made irrelevant after Core builds their own infrastructure using Rebble's work. They want guarantees that if they give Core access to the app store data, Core won't build a proprietary/walled garden that cuts Rebble out.

> It's understandable that Rebble fears someone doing this, since this is what Rebble did.

That's an extremely uncharitable take. It's not like Rebble drove Pebble out of business. What I gather is basically Pebble fell apart on its own, and Rebble picked up the pieces to keep things working.

It seems what Core wants do here is take what Rebble build/maintained and drive Rebble into irrelevance.
