I would think that the lesson here isn't that Google should be supporting its products, but rather that people should think twice before using unsupported, free products.
I believe that it was Henry Luce, the founder of Time magazine, who said that if you aren't paying for a product, then you're the product. And indeed, that's what we see with Google: They give away their products in order to sell your eyeballs to advertisers.
This doesn't make them an evil company (although perhaps other things do). They have a legitimate business model that seems to work for many people.
Complaining that Google isn't willing to offer support, free or paid, is an indication that your interests and Google's aren't aligned. They're not about to change, so perhaps you shouldn't run your service on their system.
There is a LOT of well deserved space for stuff provided "as-is", with an explicit refusal to do any support at all, but still very useful for the 'customer'. For example, large part of free software.
