But there is quite a difference between TL;DR and accusing people of wall of text/gish gallop. TL;DR is is an admittance that somebody couldn't be bothered to read something long, that's fair enough because they admit it's their choice. While accusing other people of wall of text/gish gallop is something very different; There the blame isn't put on the person who can't be bothered to read long text, and instead is wholesale put on the person that put in the effort to write the long text. The consequence is that fewer people write long form text, fewer people put in a lot of work into writing such texts, so overall we end up with less of these texts, which is a loss for everybody as the online discourse continues to become even more shallow and anti-intellectual.
