I do, in so far as it interacts with my machine. I can look at the APIs, at the traffic patterns, at whatever code is shipped to my browser. But yeah, the secret sauce stays on their servers.
But then again, comparing Google to VW is apples-to-oranges too. Google is a software company, VW is a car manufacturer that incidentally has to write code for their engines. They are not competing with each other, they are not playing on the same field. So VW having no way to use SAAS for ECUs (thank God) is as much unfair to them as their DMCA restrictions are unfair to me (the user).
