His comments were frankly quite vague. That is understandable. Startups don't normally disclose the details of the monetization plans. I meant ulterior motives in the literal sense (as I so qualified).
But as I said, this leads to a natural and healthy caution from the community as to what the real plan might be. People don't like to get on board something until they know where the train is going. The same was true of Mozilla, BTW (though their early years were such a disaster really, there was little to worry about).
