I think you're going to need to elaborate a fair amount on that take... That runs contrary to the general concensus that having freely and easily accessible information is good for people.
I think the problem that GP is referring to is that Wikipedia is currently treated as a primary source of truth with probably more trust then it should have. When it started (in the '00s) every high-school librarian incessantly warned paper-writing students to verify anything you found on Wikipedia. Eventually, we all got complacent and I believe that general attitude has mostly evaporated. Wikipedia's requirement for citations absolutly helped with this (and is a good thing) but I don't know how well those citations are vetted.
I agree that Wikipedia is good for society, and I hope it continues to exist, but I think some skepticism of it is healthy.
I don't think this is what the OP claimed up here. Anyway, you're absolutely right, and also I don't see any message on this page claiming we should take Wikipedia without skepticism.
