It's a fair criticism but I don't feel so fatalistic. This would look a lot different if everyone was opening this post on their own home server instead of chaos.social.
Unfortunately there's no way to construct a link that references the post but opens where it belongs for you. I think there needs to be a fediverse URL protocol to solve for this, ie this HN post would link to `fedi://@jonty@chaos.social/110307532009155432`, then when people clicked it they wouldn't have to talk to chaos.social, because it would be opened at their home server.
Another option could be a 'copy link for public access' that generates a static page for the purpose of sharing widely.
Journalists and media could also run their own server which is scaled for the traffic they expect, and mirror the post there. The main problem is linking to the source of the post instead of linking to a federated representation of it.
