> at least somewhat helpful information is infinitely better than having nothing at all

Maybe, at least as long as we still have a good ratio between reliable and unreliable info (whatever that ratio may be). But as long as someone can piggy-back on this reputation, and most people simply take all that info for granted, the effect of a disingenuous Wiki article is far higher than your average FB "fake news". It's that implicit trust that makes a Trojan horse more dangerous.

There is no action being taken to make this process of correcting information more open and transparent, and out of the hands of a few people. Especially since it's been shown in the past that this kind of power was sold for money in PR campaigns, or used for revenge edits.
