It's understandable that Rebble fears someone doing this, since this is what Rebble did.
Rebble took the original open-source Pebble work of thousands of independent developers, scraped it off the original store, and is re-offering it within their own walled garden and calling it "theirs".
It's great Rebble kept things alive but they seem to be fearing a second one of themselves.
> being at the mercy of a nonprofit's decisions when his company has customers and obligations.
Both Rebble and Core Devices are for-profit companies, neither is a non-profit, so I'm not actually sure which you're referring to here.
