To add some context to the other replies you’ve gotten, the restrictions were on streamers and reviewers who would be playing the game, not sure if it was an agreement for prerelease access or not though.
I also don’t know if the DDoS was related, but I think the issue was a Chinese developer trying to force non-Chinese streamers to avoid talking about topics embarrassing to or prohibited by the Chinese government.
The restrictions might not connect to any actual game content, but by even bringing it up the developers created the connection.
What gives is right, but for the developers. They managed to Streisand effect their shit, but over something that didn’t even exist in the game in the first place.
