Makes sense, I have no feeling of "open" when that (half) open software runs only on a specific Chinaphone hardware even if it has a few of its outer body lines designed in Finland.

I am hoping they will also look backward to older devices and sell the license as downloadable ROM's.

As a customer I'd be happy to pay for Jolla Sailfish about 100 credits if they make sure Sailfish runs equally good easy to get Blackberry / Nexus / Samsung devices with plenty of displays, batteries and other accessories available.
Saves the environment and gives a second life to obsolete Android junk.

Good software does not have to come free per se.
