I just cant see how this leak affects AOS4.x in any way shape or form.
It can only benefit the 68k community, which is a completely different market.
It doesn't.
Hyperion has already admitted that all of the underlying OS4 code had to be re-written, from scratch, for PPC as the original binaries were too slow. Ergo, they've done exactly what they're threatening litigation against anyone else for.
It "affects" Hyperion in the fact that an old 3.x machine can be had for hundreds of dollars, while their machines are upwards of of 3 grand (no disrespect to Trevor, here, 'cos the guy is amazing!) If 3.x gets "modernized", it's less of a use for OS4, which has a costly entrance fee.
However, Hyperion is contractually obligated to sue anyone using the sources of 3.x, illegally, as it's part of their licensing agreement. That costs them money. Cloanto doesn't care either way - this doesn't affect them, at all and truthfully anything done with it, is to their benefit.
