Is an EULA presented this way considered binding? That seems really exploitable, like making people click hundreds of links to get to the real EULA so they don't actually read it.
That was something Disney Lawyers claimed, but was never actually agreed/enforced.
Disney backed down. They still believe they have that right, and no court has ever said they didn't, but the bad publicity was too much for them in this case. They'll wait until there's a case that doesn't get that kind of publicity before they try to establish that precedent.
The fact the family can't sue. They absolutely can (edit: in my opinion).
Disney Lawyers believe they can't ( edit: in their opinion). But wether or not they can is up to a judge in this case. And not up to Disney.
So saying they can't is false until there is actual clarity.
What happens if you go there and Sony have moved their EULA page and it just 404s? Does that mean there is no EULA at all and you can play without terms? Doubt Sony woild see it that way lol.
EULA should be displayed within the same context it is accepted.
Imagine getting a 404 or 500 error. Then archiving that on archive.org (and screenshot that dialog on steam) and accept the terms. If there's any problem and they say you violated the EULA, point them to the terms you accepted.

This could be turned into a game with some kind of narrative like a Choose-Your-Own-E.U.L.Adventure. Players might try to exploit it though, so there should probably be some terms they have to agree to first.
