Siri was created by a company that does research for government agencies and companies. It was originally going to be used for military applications like telling a missile or tank what to do by voice commands, but it ended up being more expensive than it was worth. I heard an interview with a military historian on the radio, and that was his account of the origin of Siri. It may have been created for other uses as well.

The difference in Google and Apple is that the Google founders aren't documented in several forms as being hateful human beings. There aren't abundant sources of them saying hateful things about other companies and other technology CEO's. Steven Jobs was an azz. I don't really care if the next iphone will cook me breakfast, I don't want to give my money to the Jobs ilk for that reason.
