@gverdun I'm a self-hoster and work for a company doing SaaS offerings: I know that pricing a service is HARD.
Hetzner's core mission is infrastructure, which certainly allows them to do economies of scale that @nextcloud can't afford to do (yet?)
Hetzner is also using Nextcloud without contributing anything back. The GPL licence allows them to do it, but they benefit from the free R&D, while Nextcloud bears all the costs
