It's part of a larger trend that has seen traditional journalism die off in large sectors, replaced by independent outlets. Multiple reasons for this. I have a journalist friend who is quite distressed to see her profession slowly collapse around her. It's been going on for many years. Many traditional outlets have closed, relatively few trad journalists remain (compared to the old days). Tons of people have gotten laid off. Entry salaries are low, so you can't find good people to work there - not for long, anyhow. So lots of job insecurity and working with noobs with low qualifications and few options (because who would want to go into the field, the way it is)**. The AI takeover is the most recent cause for alarm, but the problems are many, and they've been going on a looong time.
You still see "legacy media" hanging on in some spots, but by and large it is being usurped by the little guy, the independent voices, cranking out content on the internet and social media. The quality of those little guys vary, of course, but it's a welcome trend. It's a long overdue rebellion against the monopoly on "approved opinion" that the traditional media held for so long. What's happening with trad journalists in the gaming space is a subset of that overall trend.
Back when I was in my 20s, I thought for a while that I might become a journalist. I'm glad I didn't choose that route.
** That's part of what happened with gaming journalism, btw. Financial decline in the journalism industry generally -> poor compensation, job insecurity -> who's going to be willing to take entry level jobs? You ended up with a lot of "gaming journalists" who had no desire to be gaming journalists, who were stuck with that job because it's all they could get. They had graduated with bachelors degrees in fields like English, sociology, psychology, history, or gender studies. They had little life experience and few options for employment, so they had to take what they could get - in this case, writing about videogames. That wasn't what they wanted to be doing, really. They were poorly paid, disgruntled, working in a low-status role at something they didn't care that much about, and were probably unhappy with their life. And it showed.
