If for some reason your browsing environment isn't/can't be configured to circumvent login shenanigans, at least for now, xitter can be read by inserting cancel right behind the X-part of the URL. Like so:

With the additional advantage of giving you a view more like threadreader.app, or something. Without having to install anything.
