The point is: Code needs to be maintained if it is to be relied on. I haven't heard good things about LLM's on that front.
There is another tool that on the surface appears similar to Defuddle called trafilatura: https://github.com/adbar/trafilatura It was OK, but I wasn't happy with it, as it kept stripping the comments sections.
For walls of text (long substack articles) I still prefer epub, and use https://codeberg.org/neo1/mkebook which I wrote, but if you love the terminal: w3m. Filters are done by your rss reader, newsboat has boat loads of options, but any decent one should.
it's a bash script front end for curl-cffi -> pandoc i.e. impersonate web-browser to download url, then convert to epub. There is also the option to use chromium for the scraper or ebook-convert for the converter. Some config and you have a (rss reader) newsboat -> calibre with a hotkey.
