Google CEO isn’t very happy that Microsoft decided to integrate its Google Talk messaging service into its Outlook webmail platform without extending a similar offer to Google for the Gmail platform. Page, speaking during the Google I/O developers conference Wednesday, said that Google always pushes to have open-source platforms that other companies can use but lamented the fact that much of the tech industry doesn’t extend the same courtesies for many of its own innovations. Page went onto say that he was “sad” that companies such as Microsoft were “milking off” Google’s innovations by not being as open with their own software.
