I used to be a CKEditor core dev. The codebase was 150k LOC of (mighty complex at times)JS and there were four of us working on the LTS(4.x) - we were somewhat understaffed, but not "we need a hundred devs for this" understaffed.

On the other hand last year I spent two weeks working on a project for which I was borrowed from another one - they had a total of 120k LOC(Java, TypeScript), twenty people and at least the front-end was a dumpster fire.

I guess people don't scale well.

I guess quality is a factor, because CKEditor 4.X might have a lot of lines but it is one of the worst library I had the displeasure to use.

I use it extensively in my current project and it is a joy. Different strokes for different folks.
