Is there a reason why the Silica components need to be open sourced?

Is there a benefit to Jolla and therefore the community for non-Jolla people to be working on the Silica components?

Does it make strategic sense?

It seems to be massively important to some people. Equally it's massively important to some people that the device can be reflashed. These seem like really minor things to me personally (I'd rather see CardDAV, better CalDAV and SIP _personally_) but perhaps I'm just not understanding why it's so important.
