I think you have a very low opinion of people and have made Wargaming into a boogeyman in your head. Wargaming has very few asks of Community Contributors. Don't make:
Racial slurs, homophobic comments or insults;
Personal attacks or harassment directed towards anyone;
Personal attacks or harassment directed towards other members of the Program*;
Dishonest comments or blatant lies about our games and products;
Usage of our copyrighted material to promote our direct competitors;
Promotion of game-breaking mechanics, cheats or exploits (by encouraging players to download, install or use them in any context);
Click bait and sensationalism, especially allegations relating to the game, company employees and their activities;
Sensitive content such as religion, sex, politics, or social issues;
Materials of pornographic, gore, death or horrifically violent nature or any other mature content of any kind;
Participation in, or condoning bullying or actions designed to incite, offend, or create unrest in our community.
Do you see anything there that muzzles people? Many (if not most) of us are very critical of Wargaming, their design features and their policies and openly so. You can't tell me that Flamu, Flambass, iChase or Yuro (just to name a few examples) haven't been hyper-critical about the game. These people aren't pulling punches when it comes to speaking of the flaws of the product. I got into a yelling match with one of the devs just this past week about the hypocrisy of one of their design decisions.
Don't mistake the ability to speak civilly for muzzling.
