I had the same exact thought. It might be that this graph represents month-by-month net income, rather than something like Net MRR. Perhaps the spike represents a large number of sign-ups for annual plans (it seems like his standard plan is $24/year) in a short period, which means he should see the same spike next year upon renewal (minus his churned customers, of course).

It might be that if he "pro-rated" the monthly payments for his annual accounts as $2/month payments for the future 12 months, he is net positive right now. It's hard for me to tell by eye from the graph, but it's probably close.
