While the Sony PSP enjoys a healthy and successful homebrew community, Sony feels it necessary to stifle them any way they can. Kotaku pointed me to the official Sony forum where they have banned any discussion of homebrew techniques or hacks for the PSP, and presumably PS3, systems.

Homebrew applications void the warranty of the PSP®(PlayStation®Portable) system, and an official area to discuss such activities cannot be provided by SCEA. Any postings that are clearly homebrew-related, such as those providing instructions on downgrading firmware updates, will be removed from this board.

Sony of course has the right to do this, but they once again show themselves unwilling to embrace a growing community for their hardware. Instead of supporting the massive value the homebrew can create, free of charge, creating everything from eReaders to GPS systems, Sony feels it has to flew its muscles and ban those most loyal from their forums.
