I don't get it either, but the reason I don't get it is it's free to give a tiny link at the bottom of the page letting people go to the other version. On mobile you don't see how many pages match your search result, so for googling an uncommon spelling you're guessing at, you don't know if it's 37 results on the entire Internet or 737,328 results. It would be sooo easy to add a tiny little link.

So why don't they do that? It should be super simple to do -- just do it! Likewise, here, it should be easy to get to the other link. I don't get their thinking here. (Plus, mobile versions of browsers should be basically as functional as normal browsers these days, so it's not like that's a good reason. Mobiles run desktop versions of sites just fine -- wasn't there just an article saying that the iPhone 7 is faster at single-core CPU tasks than any Macbook Air ever made?)
