You think you'd be privy to it? You didn't know they were releasing a phablet either until just a few short months before it hit the market either did you? The iPhone itself was a closely guarded secret too.
And there you have it. That's exactly the point. All this talk in absolutes is pretty silly when much of what you claim is based on personal taste coupled with some guessing about Apple's thought process.
There's NO proof Apple is working a car as you well know. Rumors and conjecture don't equate to proof (as I believe you've opined about other companies or their products on occasion. Remember vaporware?) All you or anyone else outside of Apple's circle knows is they're doing something in the automotive field.
It should be plain why Google bought them. They're moving into the home automation segment just as Amazon, Apple and Microsoft are along with dozens of smaller companies. It's not about ads, it's about moving more into the hardware business while at the same time encouraging more folks to buy into the Google ecosystem. Haven't you noticed that all the big techs are diversifying more, hedging their bets against any downturn in their primary businesses?
