Non-sustainable pricing is not a thing... They have VC money, when it runs out, you'll get 'shafted' (possibly, it's all expectation management of course, but they seem to set very strange expectations these days).
I realize prices will likely go up at some point in the future, but what's a fair price for something like this? It's amazing how much time this can save a developer. $10 per month seems ridiculously cheap for the value it creates. I think the market will happily pay more.
