Yea it's conceptually weird.  But in theory copyrights last way too long for the tech world.  (It's something I actually may specialize in or research heavily in law school purely out of curiosity.  It's not a workable system in the long-run.)

However, a lot of the stuff that comes up on this forum (in my opinion, although litigation is sparse precisely for this reason) would fall under fair use - i.e. no legal liability would flow to 68kmla in all reality.  This is an educational site, and if people are really using 68k Macs for commercial purpose then... well I salute you, let's say that.
