The current article, I would say, easily clears the bar for interestingness on HN, despite its culture war aspect. Interestingness is the thing we care about here (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...).
(Also, the submitter did a fine job of rewriting the title to be less baity, as the site guidelines request: "Please use the original title, unless it is misleading or linkbait - https://news.ycombinator.com/newsguidelines.html. Thanks GavCo!)
It's true that https://news.ycombinator.com/from?site=telegraph.co.uk contains a lot of ideological battle articles that probably fall below the 'interesting' line. For that reason, that domain has a penalty on it—a medium-weight penalty that we put on every site in this category, regardless of which ideology they support.
However, it does look like there have been other good articles from this domain. For example:
Elephants born without tusks in ‘evolutionary response’ to poachers (2021) - https://news.ycombinator.com/item?id=33862385 - Dec 2022 (128 comments)
So I'd say this domain is a good example of the kind that we'd penalize but not ban, and try to turn off the penalty when the occasionally genuinely interesting article does show up.
