Why are you getting mad? The economy of scale is simply not there yet because there is only a handful of us lemmy users right now. With 100,000 active monthly users, even if 1% of them bought a subscription at $17/year, it'll still going to net the dev ~$12,000 per year (after 30% google play fee) which is actually below US minimum wage. As lemmy got more and more users, I'm sure the dev would revise the pricing. If he were greedy he would just quit and work at some big corp instead of working full time on a lemmy client for peanuts.
