Reading the comments in https://blog.jolla.com/open-letter-jolla-community/ have just made me reaffirm myself in my position that it is stupid to try and go mass market. Thus "disrupting" anything should be out of the table.

So maybe the discussion is "how you would finance a non-mainstream non-Android OS" these days?

Intuition says it shouldn't be that hard. 0.01% of the mobile market should still be larger than 0.01% of the software desktop market. If all this "mobile" hype is right, at least.
