Check out this "essay" from Gamespot :
With a brand-new Harry Potter game on the way, now is the time to unpack and try to understand the impact of franchise creator JK Rowling's discriminatory behaviour.

These people are delusional.
I don't think the comparison with the article in the OP is fair, and I believe those who are attacking Gamespot's article should read it with a bit more attention (or at all, because I'm sure some stopped at the headline).
The article in the OP basically baits the readers under the guise of news to read the writer's hostile stance on a game based on a person's ideas, without providing any of the news promised by the headline, and basically proclaiming that the writer or their colleagues won't do their job reporting news about the game.
Gamestop's article is an extensively argumented (and clearly titled and labeled) opinion piece feature on the controversy surrounding the author of the novels from which the world of the game derives. It's actually quite balanced and doesn't demonize those who will purchase and enjoy the game, nor those writing about it. Of course, it's opinionated. Of course, it's critical of Rowling. And of course, it explains why the author won't support the game. That's what opinion pieces are for. You can agree or disagree with it, but the writer is expressing their opinion pretty literally in the most appropriate form in a journalistic outlet about an entertainment & art medium. It's likely one of the most balanced articles I've read on the topic, and it certainly doesn't take a stance as extreme as many's.
It also doesn't tell you "we're so much against this game that we won't report about it" (harming its developers in the process). In fact, Gamespot came out with
a proper news article about the State of Play, for those who simply want to read the news. Don't care to read the opinion? You don't have to. But it's fine for it to be expressed in the article form that literally exists for that.
Games are art, and art will generate opinions that go beyond the sphere of pure entertainment. There's really nothing wrong if these opinions are expressed in opinion pieces as long as the outlet's editorial line allows it (some do, some don't. Obviously GameSpot's does). If they annoy you so much, you can simply skip them. They're not rubbed in your face with an automatic unskippable popup. But it happens with movies, with paintings, with poetry, with books, and has happened for centuries, even in forms that predate journalism.
I haven't read a single Harry Potter book, nor watched a single movie (I've seen a couple of trailers), but today's gameplay video sold me on the game, because it looks awesome and right up my alley. I'm 99% gonna buy it at launch, and I'm likely gonna have a hell of a time if the promise of what we've seen today even comes close to be realized (besides, I tend to love games made by Avalanche). But games don't exist in a vacuum, and if there are people who don't want to play it because it's against their principles and want to express that in article form, that's certainly their prerogative.
