I am not sure FB forking OS gives them the ROI. Its a waste of effort for them. FB does not have anything to offer outside of their social network. The Home project is all they have to offer. Nothing more. Also the tech crowd do they marketing for Google. Goodwill and great services are their marketing tools and that seems to be working very well for them so far. Just look at this site and reddit to see how vehemently people support Google.
