> scaling problems due to the influx of LLM assisted coding

You mean people pushing LLM assisted coding, or github's own coders pushing LLM assisted code to production ? :-).

I am more inclined to think that it is the second, but if the reason is the first, what is particular hard to scale ? It's not like everybody is vide-coding into a single repository, so I would expect that most of the load would naturally be scalable by increasing the resources. If for some reason that is not possible, I would expect a corporation as big as Github to keep the paying customers working by gracefully denying service to the free tier, not to collapse like an house of cards.
