80% of commercial apps to use open source by 2012

I had found this intresting article which claim that 80% of commercial apps to use open source by 2012, This are not good news to application software giants such as Oracle, Microsoft, Sun, IBM etc', While for every aspect of software developing you have Open Source alternative the Open Source alternative becomes more appealing for it's robutness, and for it being free.

In IDE enviroment when coming to choose between Eclipse, IntelliJ, Netbeans most choose Eclipse, In Application Server when coming to choose between WebLogic, WebSphere, JBoss and some companies use JBoss.
Tomcat, Apache, GWT all of then are open source.

So how open source projects make their profit? The answer is from support, and not only Open Source projects, many of the software applications giants make their profit from support which can reach up to 80% net incomes.

Only in companies in which the security is critical such as Banks or Goverment institutes Open Source is not being use beacuse it might containg backdoors.
