If the person who offered helped had technical chops to scale such project. Why they would approach existing project owner instead of building it themselves?

My explanation is they did not have what is needed like tech skills or they were after taking over existing users.

Idea of scaling something up as author noted usually comes with idea that money will eventually follow. Post author is not money driven so it might be that person offering was also different in that way.

Because said user was invested in this community, and reinventing the wheel further is sometimes not beneficial. Some people are really good at specialized tasks, but might not be good at other tasks. Really good backend engineer, not so great at frontend. Perhaps they don’t have the necessary marketing skills required for growth of their own. There are too many unknowns in this story, and it isn’t fair to paint the person harshly like that.
