At least with paid apps we have a reasonable expectation of customer service and timely updates. Google's customer service is largely nonexistent, which they justify by pointing out that their products are "free". Even with products like the Nexus 4, their support was awful [1]. Simple things like updating order statuses were somehow far beyond their capabilities. With free software and Google hardware, I can't even imagine the nightmare one would have to endure to get help resolving a Glass issue.
