The Register reports about some corruption that was discovered within Wikipedia: the existence of a secret mailing list that cracks down on users why may be threats to Wikipedia administrators' power. The article goes into depth about what ensued, what happened, the reaction, and the community is pretty shocked.
Can Wikipedia still be considered a trusted source by search engines with this information known? Well, most people say that there are always flaws in these sources, but the data is still more relevant than other search terms.
The real story here seems to be the paranoia and the heavy handed treatment of dissent by the Admin group. It comes down to control. I don't think Jimbo wants to lose that.
Users will still be in control to keep the results relevant.
