the Internet Archive put the slogan "universal access to all knowledge" on a T-shirt and now I think about it every day. possibly the first principle I've encountered that I believe in strongly enough I'd get a tattoo of it.
this only works for a very very specific definition of knowledge. what's that definition again? after all, if we have no distinct referent or class of referents, the sentence is literally meaningless....
there's a thick aura of "must be fun at parties" wafting off this response, but perhaps it is in fact useful to clarify: personal knowledge exempt, like your private correspondence, diaries, photos, medical data, etc etc.
all other classes included. no government secrets. no corporate secrets. no library borrowing restrictions. no academic journal paywalls. basically if it's information that doesn't naturally belong to the individuals it pertains to then I don't think anyone should face barriers to accessing it.
