Honestly, I don't see the point in making examples out of companies with unknown profit and uncertain future. Before you jump in and say "but that's the same with Jolla", let me stop you - of course it is, but that's not the point. You are trying to support your hypothesis, that 'more transparency helps companies (like Jolla) to be successful'. Then I think that only providing an example of a company that was more transparent and also successful is relevant.
Others (including myself) have provided examples of larger (&successful) companies with less transparency and you might argue that 'when those were at the SMB stage, as Jolla is, they were much more open than Jolla and that is the reason of their later success' but then feel free to provide an example of a company that was more open and turned successful later.
