To quote from his site (linked above): FreeFlash is a PS3 application that creates a new and writable flash device FreeFlash. The original "dev_flash" device is kept to avoid issues.
We do NOT take any responsibilities for the wrong use of this application.
Requires payload with "peek" and "poke" syscalls. No version spoofing.
Finally, for those curious, PS3mlib is a high-level library designed to allow the creation of homebrew applications for the PS3, in a simple way. PS3mlib is developed to work with the SDK PSL1GHT.

unless you're a noob that always destroys stuff while navigating and copying/pasting files in a file-system. and let's face it, the noob to developer ratio is rather unproportional in favor of the noobs.
Actually, since this group released the source, we can use it to make installers for XML and eventually other firmware hacks, which is decidedly *not* pointless, since poking the flash by hand is pretty dangerous unless you know what you're doing.
That being said, the tool itself is redundant. If they'd released a static library to let us easily integrate the magic that would have been much more useful - something I'll probably do now that I have a reference implementation.
