What journalism? Most of these sites copy their content from each other or social media, and give it their own spin. Nowadays most of them use AI anyway.
Actual journalism doesn't rely on advertising, and is subscription based. Anyone interested in that is already subscribed to those sources, but that is not the audience this service is aiming for. Some people only want to spend a few minutes a day catching up with major events, and this service can do that for them. They're not the same people who would spend hours on news sites, so these sites are not missing any traffic.
