the payment is about seven dollar according to the article
This is unrealistic in practice. The Simple Dollar article cited describes making >$7 in an hour, but $6.55 of that comes from writing an article on email autoresponder marketing and writing a review of an unspecified service.

Are you sure about that? This seems to say exactly the opposite.
In fact, WOA only supports running code that has been distributed through Windows Update along with the full spectrum of Windows Store applications.
WOA PCs will be serviced only through Windows or Microsoft Update, and consumer apps will only come from the Windows Store, so you never have to worry if a program will run because you are not downloading or installing from a DVD outside of the store experience. A WOA PC will feel like a consumer electronics device in terms of how it is used and managed.
This seems like a policy adopted to help avoid angry customers making a big deal about how they cannot install this or that application from their PC. Consumers are familiar with the App Store concept.
Ergo, they probably won't be working hard to lock the platform from other applications (what little applications that will exist, that is)
