If I buy something from Microsoft, I can contact Microsoft support. I don't have to roll the dice on it being actually supported by Microsoft, or only supported by other desperate users on an abandoned phpBB somewhere.
To me, the idea of getting good support on any consumer software is laughable, and has no bearing on Google.
Microsoft does offer paid support for Windows.
For example, the person who wrote this book is probably never going to post a complaint on social media:

Why? Because big-spender enterprise customers demand that vendors implement hand-holding red-carpet VIP support for them; and most of that work is, surprisingly enough, a capital cost, not an operational expense; and so you can free-ride on it as long as it's been set up.
On the other hand, if there is any way to typewise-differentiate you from the big-spender customers, then you'd better believe that they'll have support channels you don't have.
In the other corner, I have the dozens and dozens of blog posts from HN front page from people who have gotten shafted by Google "support". And those are just the ones who had their ticket escalated, i.e. got lucky and made it to the front page of HN.
I'm not saying you haven't gotten great support. Hell, there are people out there who are happy with Comcast support. I'm just saying I've read too many horror stories to risk our business.
