I get responses to my Google Apps support questions pretty quickly and I'm just using this for my personal family accounts, so I'm not paying them tons of money. I don't think it's really fair to say they should provide support for their free tier which hosts mail for a billion people and compare it to a service that hosts, what, maybe a million?
The problem is that the burden of responsibility Google carries for those accounts is huge. The amount of money, private information, treasured photos go over their systems... with no support?
