That applies to our society at large, as well.

As for Wikipedia itself, I stopped contributing a few years ago, since I did not have the energy and the time needed to fight the systemic bias that the editors had (and have) on a variety of topics.

Also, 2021 was probably the first year in which I did not donate to Wikipedia.

I would argue corporate shills keep some information confidential by removing specific things on Wikipedia. Arguably, they do this to protect cut-throat predators in powerful positions. Which is why these cut-throat predators have an artificially cleaner reputation at the expense of exploitable people arguably. I don't completely trust Wikipedia when it comes to information about politicians, rich people, famous celebrities, specific "philanthropists", etc. Ricky Gervais, Edward Snowden, Julian Assange, Graham Elwood, Lee Camp, Whitney Webb, George Carlin, Aaron Russo, and other people made me not trust Wikipedia anymore. Wikipedia comes across as another way to put information online through rose-colored glasses to some extent for protecting people in powerful positions, such as the C.I.A. intelligence agents, by making confidential things nonexistent on public websites. People can claim I went down the rabbit hole all they want. But I know that the rise of Orwellian online surveillance, creepy phone verification systems, dehumanizing censorship, brainwashing social credit scores, decreasing human rights, increasing wealth inequality, cut-throat rulers, mental health issues from not being rich during this pandemic, and younger generations being less professionally skilled than older ones are happening internationally now. I find cut-throat rulers who have lots of money are keeping most people trapped during this pandemic via vaccine passports, not letting them renounce their citizenship, online surveillance, censorship, monopolizing the internet at the expense of online anonymity, not letting them be employees without coronavirus vaccinations despite negative side effects that killed some people or worsened their health significantly, forcing people into coronavirus quarantine needlessly that makes them financially threatened when they are getting unpaid while being quarantined, etc. From what I experienced, Wikipedia has favoritism of information that benefits the ruling class only. I would rather go to other online sources for truly investigative journalists that are not shills for oligarch-owned media companies.
