Discarding legitimate criticism based on some self-determined criteria of intellectual superiority isn't a good look. It smacks of elitism and isn't something conducive to a productive and positive community discussion.

It is unhelpful, rude, condescending, and completely fails to address the underlying problem.

I didn't make one. The sentence after "I have" was literally "you could argue the scales are different."

GitHub spent a decade asking the world to host its code with them. They got what they asked for. You don't get to beg everyone to run services for you for ten years and then have "scaling is hard" be the answer. They should be improving, not regressing over time, and they have some of the worlds best engineers and a trillion dollar corporation behind them, they don't need my sympathy.

The original question is still open and nobody's engaging with it.
