You've hit the nail on the head, that's a perfect analysis, and it wasn't an isolated incident!
But they'd been like that for a long time, since before I started there in 1990, long before Java. They DEFINED themselves in terms of Microsoft, to the extreme extent that when Sun Microsystems fell apart into separate divisions, they actually named one of them "SunSoft" to directly position it against Microsoft. As if.
The management at Sun didn't consider Java to be a programming language or software platform, they considered it to be first and foremost their primary weapon of mass destruction in their apocalyptic war against Microsoft, and they didn't consider Java developers to be loyal cherished customers, they considered them to be disposable brainwashed mercenaries in their World Wide War against Microsoft.
It was funny when Sun proudly and unilaterally proclaimed that Sun put the "dot" into "dot com", leaving it wide open for Microsoft to slyly counter that oh yeah, well Microsoft put the "COM" into "dot com" -- i.e. ActiveX, IE, MSJVM, IIS, OLE, Visual Basic, Excel, Word, etc!
And then IBM mocked "When they put the dot into dot-com, they forgot how they were going to connect the dots," after sassily rolling out Eclipse just to cast a dark shadow on Java. Badoom psssh!

Sun totally dropped the ball fighting their true original enemy AT&T, and they should have put all that effort and energy into improving SunOS and railing against AT&T after SunOS finally beat System V in the Unix market, instead of capitulating to AT&T AFTER SunOS won the Unix war against System V, and then rolling over, giving up, selling out to their mortal enemy, and becoming Solaris.
To port my favorite cross platform Apple/IBM joke:
Q: What do you get when you cross Sun and AT&T?
A: AT&T.
The SunOS -> Solaris transition was before I joined the industry and in spite of multiple attempts at reading around the topic I've never found an explanation of what happened that actually made sense to me.
> They DEFINED themselves in terms of Microsoft,
Sun completely forgot they were a hardware company. They made great hardware, but while Microsoft made it easy to develop software for Windows, Sun didn't make it easy to do the same for Solaris (maybe out of fear it'd benefit their remaining hardware enemies IBM and HP). They didn't even try very hard to build low-end machines that could do PC tasks at competitive prices.
