“Should” is not “is”. As a user, I run into broken sites regularly enough. I still want to be able to see them. I get the “let’s bury all broken legacy and hacks as quickly as possible” mindset, but when it comes to the issue of the main text of a page being unreadable, I think there is a high bar.

A lot of the reason they are considered “older sites” in the first place is because they are not heavily maintained. The thing to remember about the web is this: not all websites are “software” that is maintained. Some of them are static works similar to a movie, with static content.
