Every community has standards of behavior, even a community that claims it doesn't. That doesn't mean that every one should behave like a robot. Different personalities exist because each has something to offer. But boundaries are as important as tolerance.
For example, a site that sets a limit on the profit you can make on selling something, make it a percentage depending on the price point or something, draws some boundaries but still allowing the practice in a controlled manner. This would drive away a number of people with the sole purpose to make money of it. I am not saying i would support it, i am not saying that is flawless, but it's there. A possible solution that simultaneously draws boundaries and, also, allows for a practice/behavior to take place. You take away/minimize the profit incentive, so this leaves room for those who are interested in the community (...not the cult) for what it is.
By 'weasel' you mean sneaky or two-faced? If that's the case, everything has two sides, the truth usually lying in between.
You're last point i didn't get, English being a second language for me. You mean that there is nothing i can do?
