The presentation & insights shared (plus being located in Germany) already convinced me. A Headless CMS with the limits granted (Tier 2) is a steal (and I am shamelessly fine with it).

Only "caveat" (even though its not the business of a headless cms though):

I wish there where were some more (appealing/modern) starter templates. Simply as it supports adoption and improves User Experience.

(maybe you will consider to get a dev license from some simple but well coded templates on e.g. themeforest to give people an option to start fast - or some simple landing pages for the marketeers amongst us just looking to spin something up fast and integrate a few docs/forms/articles).
