In principle, if you want the post and comments without JS you can just pull the underlying ActivityPub document (application/activity+json). I made a command-line browser based on this idea: https://github.com/bentonedmondson/servitor

That's unfortunate. Sites used to not need JS to show static content.

Yep, the web used to be for distributing documents, but now it is becoming/has become more of an application VM [1]. But ActivityPub is a nice format for the document distribution use-case; it is a superset (in terms of features) of semantic HTML [2] and RSS and has higher level semantics (comment sections, profiles, etc) and no server-provided scripting nor styling.
