There are going to be a LOT of content creators that generally don't have any problematic histories that are going to be playing this game, unfortunately.
And honestly, this is something that kind-of concerns me as well.
I apologize for the lengthy post, but this particular question has been on my mind for a long time now and I feel the need to bring this up.
Is: "This person played Hogwarts Legacy." Going to be the new: "This person follows problematic people on Twitter?"
I am not touching Hogwarts Legacy with a ten-foot pole. I don't think other people should be buying Hogwarts Legacy. But something people should understand is that I only have this position because I've been made aware of the extensive amount of damage that JKR has done. In fact, had it not been for trans people on ERA, I would probably have only gotten the occasional blurb about it here and there might have ended up ignoring it entirely, not knowing the full truth about the situation.
It is very possible that other content creators, along with many other people in general, will not have the same amount of knowledge people here have about JKR. Content creators that have particularly large audiences receive tons of messages from people every day, so who knows what mixed messages they're getting. Who knows what news sources they keep up with and what information they're getting? Aside from being able to see who they follow and what they retweet on Twitter, we can barely tell. We are not those people and we don't live the same lives that they do.
So what's the solution?
You could argue that a mass-unfollow campaign would get them to take notice of the situation…but I think that will do more harm than good. A campaign like that would bring about needless hostility and have other negative consequences. They might find themselves seeing how other people are reacting and use the same: "Supporting the devs" excuse, because it's a very popular thing for people to say in their defense, no matter how weak it may be. Worst-case scenario, it could get some content-creators to get harassed to the point that the actual message that needs to be sent would get lost. Even worse than that, it could cause people on the GC-side of things to bring them over to their side with their propaganda, turning who could've been a potential ally into an enemy.
Now you could also argue: "Well, if they were brought in by their propaganda then they could never have been an ally in the first place." To which I have to say, don't underestimate what propaganda can do to people. Ordinary, good-natured people can very easily be taken in by the lies and flattery by others. Especially when they feel attacked.
My suggestion? Well, to do what you did in your edit, basically.
If a content creator you enjoy is going to be playing Hogwarts Legacy, send them an email, talk to them on Twitter, get in contact with them in any way. Be as thorough as you can in talking about how severe the damage that JKR has done. Give them sources. Speak in as good faith as you possibly can. If you still feel uncomfortable and wish to unfollow them, that's on you and you alone and I certainly won't judge you for that. But I do ask that, if you really enjoyed that person's content, and if they hadn't shown ay really red flags until then, make a conceited effort to make them aware, first.
Hogwarts Legacy is sadly going to be a popular game. We're not talking like, popular indie game level on Steam here. This is potentially going to be a mainstream mega-hit, and there is no way content-creators from all over aren't going to take advantage of that. Whether they like Harry Potter, or want to play a popular game for views on Twitch. With tensions running high and especially with all the transphobia in the UK running rampant right now, I can't imagine how people in this thread must be feeling, being constantly under attack like that every single day. I understand how angry the Wizarding World as a brand must make you, knowing JKR uses it to give legitimacy to her arguments and stand at the forefront of a full-on hate movement.
Situations like this though, need to be handled as delicately as possible. My hope, is that people will think and talk to content creators carefully about what JKR is doing. My fear, is that some people will use Hogwarts Legacy as a reactionary means of lashing out and trying to launch attacks on people.
I would like to believe that fear is unfounded.
