The current policy is the healthier one. Wikipedia should by and large reflect the common consensus, at least on a zero-order approximation, not try to enforce the "correct" view
There's no reason to put correct in quotation marks here if nobody disagrees other than by mere habit. And if that is so, it is proper for an encyclopedia to use the correct term. That's why the Britannica uses "Ockham's Razor". Using the Google popularity test for article titles is unprofessional.
To pick an analogy: Based on Hollywood and TV movies, many people believe that cars will explode after a heavy crash, which often leads them to escape the vehicles quickly instead of trying to save others who are still in them. Wikipedia will correctly point out that it is an error, because there is nobody who factually disagrees with it.
For example, I know about the term "Pennsylvania Dutch" and have seen it used in many contexts (social, political, commercial branding, etc.) whereas "Pennsylvania German" is just not a term in use.
Try googling for it.
Similarly, "Occam's Razor" is by far the more prevalent and *preferred* spelling for the term by English speakers.
16K vs 26K in Google - hardly "by far" the more prevalent and preferred. What matters is not just the number of sites, but also the type of sites.
