That’s a valid legal question.
The AGPLv3 license applies to the repository as a whole (the software architecture, the visual logic blocks, the UI/UX, and the compiled system). The license is there to establish a rule: if someone takes this infrastructure, modifies it, and hosts it commercially for others, they are legally obligated to keep their modifications open-source.
That being said, I don’t harbor any illusions. I am well aware that in the real world, bad actors might just fork it, strip the license, and run a closed commercial service anyway. But having the AGPL in place is a statement of the project’s ethos and gives at least some baseline legal leverage if a larger corporation tries to blatantly rip it off.
