The mastodon client I really want is my web browser. I want my web browser to be able to go to a mastodon web server and see HTML of posts (and responses! so no, /embed is not a solution) with actual text. This traditional form of interface was removed in most mastodon implementations from version 3 and on for some reason. Requiring execution of complex code, either in the browser as javascript, or on your computer as a native client, is not cool. At least for twitter there's nitter but there's no easy way to read mastodon posts/threads.
