Great hilarity, with the AT&T joke.
I would add things are rarely only one thing. Did Sun cherish Solaris and Oak/Java developers? Absolutely. Did they cherish all of them equally? Absolutely not. Did they also see them as disposable pawns in a war against MSFT? Not as much at the beginning, but pretty much exclusively towards the end.
You still can't pay me enough to use Eclipse. Well, that's not completely true. I got paid to use Eclipse a couple jobs ago. I wasn't happy about it, but I was too lazy to write something better.
And there's probably another discussion in here about how the market changes and if you don't change with the market you turn into IBM or CA. (Tempora mutantur, nos et mutamur in illis.) IBM came late to the PC party and had to sell it's soul (use an open architecture) in order to not be steam-rollered by Apple (and Commodore and Atari of all people.) MSFT famously came late to the intarwebz and it took Bill Gates to personally beat up some vice presidents to get them to focus on it. I think we just violently agreed that Sun was too focused on defending their web dominance from MSFT that they sort of ignored Leenucks for too long (and as best I can tell just ignored mobile.) Imagine what the landscape would look like if Sun added third-party intel servers as first class supported systems for OpenSolaris (and maybe started OpenSolaris a little earlier.) That was probably too much for Sun management to put their brainstems around at the time.
