You mean if you're interested in academic medicine at certain institutions (read: prestigious institutions), right? Nobody's denying that the most prestigious institutions do tend to have a preference for one another (no matter how unearned).
But I think SDN also forgets that academic medicine really just refers to being at an institution where you're involved in the training of medical trainees and/or some form of research. There are TONS of academic medical centers/hospitals where there's not as much prestige but faculty are involved with teaching and/or research.
Slightly unrelated, but it's the same with competitive specialties and fellowships. People seem to forget that most of these specialties also exist at the less prestigious schools. And if your goal is to match in that specialty but you don't have to also be at a prestigious institution, not going to a prestigious medical school isn't going to hurt you. I urge you to go look at some of the match lists for nsgy, derm, ortho, etc programs at less prestigious medical centers/hospitals. They're full of people from regular degular medical schools lol. Here are some examples:
