Facebooks moves looks like it might be trying the EEE strategy MS used on the web, much to its detriment as any web developer knows. Itís moves like this that make us have to write 3 or more sets of CSS tags "-moz-", "-webkit-Ē, ď-ms-Ē, etc.
For all we know Facebook is starting to pivot into developing beyond its core competency. It is no secret that FB users are leaving in larger numbers because they are fed up with its constant encroachment. When the golden goose dries up, FB has to be ready to switch to another lucrative business. And devices powered by a FB OS with a ďbuilt inĒ pool of tens of thousands of developers (HHVM) might be a feather in the cap of a Facebook hardware platform. This all kind of makes sense, but it is speculation at this point.
