I signed up for an account just to respond to this. I run a small, low-budget, lean startup and we were banking on the starter plan lasting us at least 6 months as we gradually scaled. You cited in the blog post that making this change was supposed to "reduce entry costs" but how has this happened?
Just the limit of the old free plan would cost you more than the old starter plan! The limit of the old starter plan would cost like 7x as much now. Can you give a single use case under which the new pricing is cheaper for entry level customers?
