This doesn't really have much to do with Forza Horizon 4. As, if it's like Forza Horizon 3, you will still be able to play the game online and offline. This is what the stop killing games wants the other publishers to do.
I’d go one further: The movement can come across as whiney and impossible to please when it echoes the message in a super-blanket way in places it doesn’t make sense, like this one.
It’s like protesting government actions with “All government should be abolished so we can ALL BE FREE”.
Was going to be upset because I played the game through game pass and bought the Lego dlc for it but not the actual game. Looks like they're sending out free copies of the game if you are in the same boat. So that's good.
