There's a big distinction between venting your disappointment, or annoyances and just electing to take the stand of attacking both the community and/or the developers. It's also quite glaringly the absolute worst thing you can do for yourself, the developers and the community you're apart of. Inflammatory remarks, regardless of whether constructive will just get ignored because they serve no purpose whatsoever. I'm pretty sure the majority of the community is of the appropriate age where this should be something seemingly obvious.
An echo chamber will only occur if their purpose is to very selectively listen to feedback, which I'm pretty sure is not the case. But whilst we're on this final section though. Arguably there is already a level of echo chambering going on within the community. Taking into account that in many cases views opposing are either met with nonsensical remarks such as "Find a new game", or "White Knight." These levels of remarks serve no other purpose than to attempt to undermine an argument. - Arguably in this respect, some of the community are already in the state where they're unintentionally creating this environment.
What is not a great situation is to create and entertain the notion that your disappointment, or disapproval in a product gives a token to be disrespectful and rude with your criticisms.
