That article irks me as it makes no sense. First, there in fact is very little room for commercial software in the cloud: the clouds are built using either in-house developed tools, open source software, or combinations thereof. Second, what people run on top of cloud platforms is almost always open source software: in fact, it would be hard to see open source distributed computing projects such as Hadoop and Voldemort gaining much traction without "the clouds". Third, there's a whole business model for open source software: the software itself can be released free (as both in speech and in beer), while the customer would be charged for the service of running the software on vendor's premises (the vendor nets a profit, while the customer still as they don't have to build out the hardware infrastructure/perform systems administration/customize the software themselves).
