"For reference, we have about 10x the amount of code and 4x the number of screens on each native platform". So the amount of code and the complexity is substantially more difficult than you describe. You probably also don't have as rigorous AB testing, logging, internationalization, contributions to open source, etc.

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.
