That isn't what they are doing at all. You read whatever you read incorrectly. Apple is deprecating their own version of Java on OSX.
Isn't it also the only version of Java known to run reliably on OSX?
If not Oracle, then the OpenJDK community. Either way, if it's wanted badly enough, it will happen.
The long-shot bet would be an LLVM/VMKit implementation that is clean of Sun code.
I'm writing this on an MBP and might well post from a Macbook Air someday but I think Hacker News is giving Apple a very non-Hackerlike treatment. They're clearly moving their computers to a much more controlled iPhone/iPad model.
Oracle might try to remedy this situation eventually, but my bet is that it will be too little, too late.
Supporting multiple similar runtimes (HTML+JavaScript vs Flash vs Java vs SilverLight vs somebody else's kitchen sink) may make sense, but eats disk space, and, once people start using them, RAM and CPU bandwidth (due to less sharing of code between programs).
Including Flash and Java made sense a couple of years ago on the Mac, but when designing the iPhone, Apple, as they always do, revisited earlier decisions, and decided they should go. Given RAM constraints, I can see why.
On these new MacBooks, I guess Flash was dropped not because of RAM constraints, but because the disk is relatively small. It is but a tiny part of that 64 GB, but they probably must make many small cuts to give the user as much space as possible for his own stuff.
How about support costs. If Apple doesn't supply it, and you install it, then have problems, who ya gonna call ?
I'd say, call Adobe. Let their support call numbers spike off the chart.
If that's true, it still doesn't help mot users. I would guess that most users will install Flash pretty quickly after getting their laptop. They will then be subject to flash on all webpages, negating any battery savings.
Adobe needs product leaders that care. I think Apple is not so subtly trying to send them that message.
This comes at about the same time that Apple deprecates Oracle's Java from OS X. Is this a general move against preinstalling third party libraries or unrelated?
Perhaps it signals Apple's belief that both technologies are moribund, if not dying outright.
Perhaps it stems from Apple's claim that Flash is bad for battery life. This can matter even when there aren't obvious Flash widgets on pages you visit. Flash is used for ads and any number of tracking processes.
As much as some will love to pour hate on Apple for this move I think the real failure here belongs to Adobe who has been satisfied to sit on their laurels blaming Apple for victimizing them rather than delivering a compelling Flash experience on mobile devices or OS X (3+ years after the iPhone's release only now is full Flash running on mobile (Android) devices and reports are mixed on the experience).
