Read their financials, the gross margins for services are listed in every one of their reports. And the $99 and ad revenues are service revenues. So their audited financials say, taking all of those revenues, that services expenses are roughly 32% of their revenues. Obviously this doesn’t include administration costs, interest costs or taxes. 32% of 30% is 9.6%, so it’s possible that’s their break even level, or even a little lower if App Store margins are higher than other services. But it’s unlikely because it’s likely the billions in the Google Safari placement check is close to 100% margin, meaning the rest of services has to have margins well under 68%.
