Paywall? Disable JavaScript

Try the article reader mode in most browsers first. A lot of these things keep the page content in the DOM, but just add garbage on top of it to make it difficult to read. In cases where content has been actually removed from the page, viewing the page source - not the current page structure, but the actual page source code that the browser downloaded from the server - can also work.

Disabling JS is kind of an extreme step since it will affect every open tab in the browser, so if you have something playing music or other audio in the background or something like Slack open and waiting for important messages, they will likely break.
