Right, and to add on that this is really the perfect case for AGPL in that the company isn't a rocket-ship trajectory startup or anything, it's a single developer who maintains it as a side project and aims to bootstrap & operate at a profit (I think he recently transitioned to working on FOSS full-time so technically not a side project anymore). In other words, the risk is closer to the risk of a side project failing than the risk of a giant corporation failing, and the need for flexibility to pivot to different funding models is lower or nonexistent. There's no venture capitalists to appease. Presumably, if the founder decided he could only profitably run sr.ht by turning it into "open core" like gitlab or proprietary like github, he would have simply given up the project.
