The main problem for Jolla focuses on two things:
1: Economic model: what did they try to do to earn a stable continuous amount of income? Advertisements? Subscriptions fees? A steady flow of new devices with the manufacturers paying a fee per device for Sailfish?
If you don't get it right to have a stable income...well, that just ends all. Period. There's no debating about that.
I think Jolla should let their contributors pay a small subscription fee for the updates. Let's say somewehere around €5 per month or less.

2: open source, but not regarding to news. I've read big issues on several channels, but not from Jolla itself. Do they have to hide something? I've asked many times for the stock internet browser to have the option to change the user-agent (a base feature for a mobile browser), without any response. "No, it's not possible", or "No, it's not our focus now" is a response, rather than no response. Jolla, talk please!
