This makes me sad. I understand where people are coming from, but at this point people should realize that you cant build business on someone else's free products. Its for a reason that big companies pay money to get, sometimes even open source software (Red Hat) or get certified machines (from Dell/HP).

Building a business/livelihood is very different from experimenting. Experiment all you want with free products, but if you're gonna do the former be very sure of what the risks are.
