I feel like you're misrepresenting the results, though. Note in particular that they "reached their twelve month target of 100,000 clients six months ahead of schedule." If I had to guess, I would say that users were mostly dismissing the ads out of hand, and Blyk was unable to charge acceptable rates for ads, but I really don't know. It's also not clear how targeted this advertising was--it may be that the sacrifice was in UX only rather than privacy, in which case it's not exactly relevant.
