Firstly, just to be clear, in some ways nothing has changed. If you are some kind of school/university or non-commercial organization, we offer the course to you for free (assuming you're located somewhere where we can get to you easily). Secondly, however, if you're some kind of commercial company, you now—for the first time—have an official Sun course at your disposal. The content of the course is the same as before, with the difference that Sun now officially supports it.
Community trainers, such as Anton Epple and Aljoscha Rittner and other NetBeans Platform Trainers who do not work for Sun are also still supported. In other words, we have a hybrid model whereby Sun offers the above course, providing official Sun staff (such as myself and Jaroslav Tulach and Tim Boudreau and many others) to deliver that course. In addition, we can call in the help of community trainers, who can also be reimbursed for their efforts.
On top of that, the NetBeans Platform trainings offered by the community trainers (i.e., non-Sun employees), such as this one by Eppleton are completely valid too. They simply fall outside of the Sun ecosystem and can function independently, since the NetBeans Platform, as well as all the related training materials are open sourced. In other words, anyone can (and is encouraged to) take the training materials and make money off them. We also have a program for certifying NetBeans Platform trainers, which means Sun will officially endorse you as a trainer, by adding you to the NetBeans Platform Trainers page, so that prospective clients of yours can see that you're qualified to train them.
Finally, all of this means two other important things. Firstly, the NetBeans Platform is now an official part of the Sun Learning Services revenue stream. Secondly, commercial organizations interested in taking the course should now take confidence knowing that Sun officially endorses the NetBeans Platform training. Implicitly, the NetBeans Platform as an area of interest separate from NetBeans IDE is thereby also endorsed.
