Sorry to say it, but again the author is pointing out the obvious. Open Sourcing the java language does nothing in terms of technical achievement, other than buying Sun some PR.
As the author correctly points out, business users will standardize on known distributions and JVMs. (Sun or IBM) for example.
What this really does is to give Sun some PR and some "street cred" as being part of the Opensource community.
In terms of control or influence, it does very little.
Its a well written article, yet it states the obvious and doesn't answer the question of how a company will make money in an open source market place.
Note that there will be those to shoot from the hip and cry "services", but then again, the majority of them haven't tried to run either a services group or company... ;-)
Its a strange, dangerous world that we live in these days.
But hey! What do I know? ;-)
