OK, seriously guys, give me a break. Posting information about leaked Panther seeds is not going to make Apple cancel the seed program, nor is it going to hurt Apple as a company.
Apple has done this to themselves. They've *ALWAYS* been a secretive company, unlike Microsoft which often does public previews of its upcoming software and stuff. Due to the secrecy, and due to the fact that Apple has come to have a loyal group of followers, these followers want to know about everything that Apple is going to do next. They want to be the first to know about what next new innovative product Apple has around the corner. Apple just feeds the fire by continuing to be secretive and by continuing to not comment on rumors.
I'm not saying this is a bad part of Apple's policy. They do have every right to protect their products, and to release information about them when they see fit.
But Apple rumors have been around for such a long time! MacOSRumors.com has been around since at least 1997; same with AppleTurns.com, which used to be more of a rumor site than a satirical Apple news site. MacNN used to run a rumor site; AppleInsider's been around for a while. So why do you guys think that more rumors are going to hurt Apple? They're not! Apple has had to deal with this for a long time, and no matter what they try to do, Apple's not going to get away from it. So Apple has no choice to accept it.
Seriously, though... there's a small dedicated group of rumormongers who like to go to ThinkSecret and MacOSRumors and read about all the new things that Apple's been prototyping (like the G5 dodecahedron...

). But the average Mac user couldn't care less about all this rumormongering. And we're already dealing with about 5% of computer users anyway, so there's a relatively small number of people who read Apple rumors. So the leaking of all this information is really not going to jeopardize Apple's business. That argument is specious, at best.
Let me stress one more time that Apple rumors have been around for many years, so having rumors around right now is not going to be any more of a problem to Apple than it was back in 1997.
And if you believe that leaking information about software development will hurt Apple, then there's no choice for you but to admit that leaking information about upcoming HARDWARE products will hurt Apple even more, necessitating the entire shutdown of MacRumors. Do you really think that MacRumors has *THAT* much of an effect on Apple's business? We often don't even have any of the correct information! Apple still pulls off surprises (like the original iMac, and the introduction of the 12" and 17" Powerbooks). What about Exposé? Everyone was just going bonkers off the walls about piles, and it's still nowhere to be seen in Panther. Yet Apple pulls off the surprise unveiling of an *AWESOME* new feature that is going to be so much of a better timesaver than piles ever could be.
At the most, all that rumors do is lag sales just before big trade shows, but that lag in sales is offset by pent up demand for upcoming products AFTER Apple introduces them at major trade shows, so it all evens out in the end. Apple probably even benefits from the publicity that rumors generate, especially when publications like the NYTimes get in on the rumor frenzy.
But, no, rumors do not hurt Apple in the least.
