There is a saying in my native language that goes something like "If you mix poison and milk, the milk will turn poisonous, instead of poison becoming milk (aka beneficial)".

I guess, to convert it into this context, we can say that if you mix the high minded and infantile (which I think is what Internet and social media did), the high minded becomes infantile, instead of the other way around.

there is no 'sin of maximal inclusivity here', the gate is broken, but primarily because it was largely an honor system before, and no one has the motivation or resources to really dig into a lot of these papers.

in no sense was it corrupted by the desire to include a larger population in journal publications.
