I do believe that there were forum threads about where and how to get Intel builds of OS X that included torrent links, et cetera.
Just as our webmaster and admins would be responsible if someone were posting piracy and warez links here, so was OSX86. Remember that they weren't doing any reverse engineering on the system, only replacing bits with the corresponding part from Darwin, and adding a few little bits of code. I'm pretty sure that's NOT a SLA violation, as there are myriad OS X "enhancers" that use Darwin code, such as XDarwin and Darwine and Apple hasn't said anything about them in the five years that they've been around.
Also, OtherWorldComputing's XPostFacto serves a similar function to OSX86... allow OS X to run on "unsupported" hardware. I'm running 10.4.5 on an original 300MHz clamshell iBook. Remember that 10.4 "requires" a built-in FireWire port. XPF can also make OS X boot and install on totally out-there hardware. I have a Power Mac 6500 (250MHz PPC 603) which XPF can force 10.2 and older to run on. So much for "G3 required".
And Apple hasn't said anything about XPF...
