It's not a text article though, it's a public microblogging forum like Twitter, implemented with a protocol for which this just happens to be a web interface. And a forum with more features than the one we're on, most of which would be quite inconvenient to implement in a purely static website.
Now, maybe what you're actually trying to say is that the content of the Mastodon thread should have been static website instead. That might be your preferred method of consuming this information, and that would be a valid desire. I can't say I'm a fan of twitter-style threads either.
Having said that, that does not take into account what the author of the thread wanted to accomplish. In all likelihood they're on Mastodon precisely because they want interaction with strangers. Otherwise they would have written the static website version. So it's a matter of misaligned needs.
Also, note that Mastodon is built on a protocol - it does not need a web app. So you could build a thread unroller or use an existing one to meet your static website needs, although I have to warn you: current implementations use JavaScript for that[0].
There’s a big gap between “static website” and “requires JS to render anything”. All you need is “serves meaningful HTML which it then enhances with JS”, possibly in the form of server-side rendering (I think it uses React?).
