My point with the example was to show that Wikipedia is a public resource. It's not "that other guy's" responsibility to fix it. Every editor is a volunteer. If you have the energy to complain about a public resource that you benefit from for free, that is maintained by volunteers, you absolutely should be shamed for not chipping in yourself and instead writing about it elsewhere. As the famous line goes: "patches welcome".
Here we are in a topic that actually documents the hostility people encounter when participating in Wikipedia, a topic that provides overwhelming anecdotal evidence among the comments that people are being actively discouraged from contributing to Wikipedia by hostile admins and topic campers (something I have personally experienced) and you pretend the actual problem is lazyness.
Except that WP has its own arcane laws and policies used to great effect by regulars to ensure no outside voice is given a say in truly contentious articles. e.g. If you try to get involved, you are a "single purpose account". If you contest the veracity of a source, it turns into a meta debate where you are expected to provide an alternative view that is nevertheless considered a reliable source by everyone there who thinks otherwise.
It's a trap, because it ensures the only people who direct it are the ones who also have time to fill the site with unimportant trivia and camp out. Unsurprisingly, anything to do with the current culture war is a lost cause.
I also find it funny to see what sort of living persons have biographical pages there, as it seems often the result of mutual backpatting in various niches.
