Does he "care deeply" about this? If we look at the direction they've taken in recent years, and the products they've launched (and/or killed) - how many of them demonstrate a "deep care" about this mission? How many of them are even tangentially related to this mission?
(The projects that Google undertook in the early days --Earth, Maps, Mail, digitising whole libraries, photographing the world for StreetView-- definitely showed a dedication to this mission statement.)
