Given that the blog is on windows.com and it mentions MSDN, I think the title should include Microsoft as well. I was actually confused/befuddled seeing the juxtaposition of Google and Mozilla in the title, and windows.com as the domain in brackets to the right of the title.
The submitted title was "Mozilla, Google, others team up to make MDN Docs the place to go for web API ref" which is actually an uptick in misleadingness, as you and others pointed out. Submitters: please don't do that.
