Although, handling it purely pragmatically, there is no other concise source of information as vast as Wikipedia's concerning so many facets of life as well as sciences that is far enough from feelings' reach that is pretty well-written as the only possible bias present is also factually incorrect (as opposed to ideological topics).

I understand that supporting and reading articles from a source which you know is blatantly lying or otherwise obstructive or manipulative on other topics is a difficult undertaking but we literally have no other option . There is no war but the war against illiteracy to be won. Education, information and intelligence is man's best friend and until a better alternative arises for the masses (e.g scientific articles do not count as an alternative, Britannica is only in English) the one we have should we stuck with, and its quite well managed too.

Bias in itself is eternal, and holding any entity to a standart so high is illogical at best in my view. If there was no Wiki, would you think the many blog pages filling its space would be absent of the very bias you're talking about, but worse, would they have had any factual backing?

I don't think simply being absent is logical. Sensing ideological currents, bias and being primarily a lurker rather than participating will have the same mental benefits without limiting your knowledge.

You can see a similar thought-process behind Tor bridges so it is tried-and-tested. Noted that it is a much more difficult feat to accomplish in a full blown browser rather than network layer.

Goes against the very nature of the distro. I very rarely see assumed defaults in Arch, and they are almost always opt-in. Mind you, you need community provided helpers to automate AUR building, its that barebones and I'm sure there are people who manually build / use custom scripts to build every package.
