Would love to and I have no objections to it. I work on some popular open source projects. It would be very difficult to work on this project while growing a community for it as well(this has been, for the most part a side project).
Nonsense. If you're hoping to earn your living on this, and it's good enough that people want to use it, they can cough up $5 a month for it, or use the free plan. And it looks like it's attracting some good attention...
People have to realize that even open source devs have to make a living, and not all of us are fortunate enough to work for an open source friendly employer. In fact, if you're like me, a single well-paying project like this one would greatly free up your time available for open source projects and increase your open source contributions.
I've seen what happens when open source devs rely solely on user donations, even ones with really popular and useful projects: they starve.
Side note: assuming the cost is indeed $5 and $19.99 a month, you need to make the "per month" explicit. Right now, if someone signed up and you dinged them for multiple months, they could technically but correctly lodge a complaint with your payment processor for illicit charges.
