The UX can be changed, right? Use short media by default, provide an alternative (some form of "expand" button, like in gmail's compose interface?) for longer posts... same with how articles work in Hometown (https://github.com/hometown-fork/hometown/wiki/More-content-types).
And besides, "the fediverse" doesn't bend to Mastodon's UX. Other software & instances (like https://writefreely.org/) already use long-form posts - and IMO Mastodon that should support them. Otherwise, it's bad UX.
Also, char limits are bad UX.
@james yeah, the thing is, mastodon in several cases supports content (like longer text and even formatted text) but just chooses to limit it for it's own users. I think it's important to remember that Eugene _wants_ it to be twitter, so if that's the place he's coming from, that influences where the software will go. I'm personally loooking for a AP feed reader, that I can also easily publish and extend.
