This blog post is way off. The issue isn't that Google Maps couldn't find Sambisa Forest, it is that it has an issue with how it handles auto complete and pressing enter without selecting the choices it brings up. It quite frankly looks like a bug. You can see for yourself here: http://i.imgur.com/vX1xqp2.gif
I disagree that the blog post is way off and I think the issue is that google can't find Sambisa Forest (it can't - as your gif demonstrates). It can find, "Sambisa Forest Reserve," which is great, but not the point of the blog.
They are saying that google's ability to take natural language requests (sambisa forest, in-n-out east bay) and come up with an answer that corresponds what you searched for has seriously degraded. Personally, that is consistent with my experience.
What is causing the problem (bug, difference in focus, etc) is also worth discussing. Why does google have so much trouble finding answers to queries that seem straightforward? Why can it suggest "Sambisa Forest Reserve" (based on "sambisa forest") and then have no idea how to find "sambia forest?" The title might be a little grandiose, but I think it's a fair question.
