Was AirBnB not one of the first companies to champion server-side rendering of React apps? I think you’re listing apps that are actually a bunch of SPAs glued together (each page is super complex and an SPA of its own right).
I remember being pretty interested in it at the time.

I don't know about AirBnB. Booking has a little bit of interactivity that is more annoying than helpful¹, like the GP's example for Reddit. None of the others can be described as "applications".
1 - The map is good. The stuff on the map is very good. The map itself is an SPA. For all the rest of the site, if they removed all the Javascript it wold be an improvement.
Overall, I would count that as MPA?
The apartment pages seem to be client side rendered. When I CTRL+u and look a the source code, I see a lot of JSON and not much HTML.
