I think another element is if you are a single or part of a small team of developers you realize quite quickly the value IHP adds to your project in terms of time savings:SES, Sentry, deployment... Etc. Also When you rely on IHP for anything in production you end up exploring some of the more remote corners of the design and I've found the quality is still very high even for niche features. From this perspective paying the monthly fee to keep the team developing IHP interested becomes a very good investment.
