To my knowledge, coverage of the journalism industry isn't a huge part of the news cycle, certainly not as much as coverage of the software industry is!
Anyway, there's plenty of stuff on HN that isn't about software development: in the top 10 front page articles right now, there's a news story about an Albanian cyberattack, a link to WikiHouse, a warning about a potential privacy breach on virtual meeting software, product announcements for YC Summer 2022, etc.
It's more "stuff that may be of interest to people in the software industry", and I have no trouble imagining how you could fill a link aggregator with "stuff that may be of interest to writers".
