no offence as your a Sun employee, but isnt that what makes most Sun technology actually successful?
Depends on your definition of success. Open source software has certainly been a successful way to get Sun technology into many new hands, just like iPods have been a successful way to get Apple products into many more hands than Macs ever did. But it's certainly not where most of Sun's revenue comes from.
Contributions from Sun to its open source projects like OpenOffice, Java, Netbeans, dtrace and ZFS, in general, still greatly outweigh those contributions that come from outside Sun. So if Sun/Oracle was suddenly to decide to stop any involvement with, say, OpenOffice, and turn it over entirely to the community, all I'm saying is that development would inevitably slow way down for a while, and may stop altogether if there weren't enough people interested in doing the work to keep it alive.
Disclaimer: Just to make it clear, I have absolutely no knowledge whatsoever of what Oracle expects to do with OpenOffice or any other open source project should the acquisition be completed, so this is pure speculation on my part
