Re: It's only a good idea for Google.
Is it? In my family of 4 I'm the only one who still uses a Windows laptop and that's to run Visual Studio and IIS.
I totally understand the point you're making but it misses the the fact that a Chromebook is a consumer device. A full stack Linux or Windows machine is never going to be as convenient and easy to use as a Chromebook. Though I would never own one the reality is that it's a consumer pc that satisfies most user's needs.
Don't allow your distrust of Google to impede your ability to think objectively about things.
