I understanding them selling a lot of IP to Fitbit to pay back their debts and settle bankruptcy, but I really feel all the source for their app/store-services should have been made open source instead, prior to this announcement.
That way at least their customers could try to hack together stuff or make mirrors of their app repos to keep their devices functional.
This could also be an issue on Fitbit's side. Open Sourcing all the IP makes the deal less enticing to them (that's the first order analysis, but there's arguments in the other direction too)
