I just read the leaked Mac App Store guidelines. Scary. Really scary. Let me comment a bit on the prose, that really looks like a fake but just in case it isn't...

Apps that crash will be rejected
The number 1 crashing app for me is... the OS X Dock! Let's reject the Apple Dock.
Apps that exhibit bugs will be rejected
Ok, the Mac App Store will be empty then...
Apps that include undocumented or hidden features inconsistent with the description of the app will be rejected
Goodbye easter eggs
Apps that are "beta", "demo", "trial", or "test" versions will be rejected
Goodbye 0.x and demos currently available on http://www.apple.com/downloads/ (that was last updated 15 days ago...)
Apps that duplicate apps already in the App Store may be rejected, particularly if there are many of them
Run, run ! First in, others out !!! This is totally crazy, a denial of how works this industry.
Apps that are not very useful or do not provide any lasting entertainment value may be rejected
Very useful ?!? That's so subjective I can't believe it's here.
Apps must be packaged and submitted using Apple's packaging technologies included in Xcode - no third party installers allowed
Ah, here we go again. Just lame and counter-productive
Apps that download or install additional code or resources to add functionality or change their primary purpose will be rejected
Goodbye network-based installers
Apps that require license keys or implement their own copy protection will be rejected
That's a joke I presume ?!? So Apple's going to control the whole thing ? Seriously ?
Apps may not use update mechanisms outside of the App Store
I think the Mac App Store will never have my own apps
Apps must contain all language support in a single app bundle (single binary multiple language)
This is hilarious ! Hey guys, you work in one language only but instead of downloading a 1meg bundle, you'll need a 7megs bundle juste because Apple has decided so...
Apps with metadata that mentions the name of any other computer platform will be rejected
UUUUH ??? Are they nuts or what ?
Apps with app icons and screenshots that do not adhere to the 4+ age rating will be rejected
Ok, live proof, they are nuts

At this point, I don't even want to read more of the document. If this long list of stupid rules is not a fake, Apple is evil and a danger for the software industry. Most of the software I use on my Mac would be rejected. They have a licence screen, use a theme similar to iTunes, are localizable only with an extra download, are updatable through their own web site, mention they are cross-platform, are packaged using ten different mechanisms, all have bugs, all crash from time to time including Apple software, etc. Just pure crazyness. Period.
