OS 3.1 source has such niche value that for all intents and purposes it is non-existent. Opportunities to commercialise are even fewer.
20 years ago it would've been awesome, 10 years ago there might have been some residual commercial interest.
Today? It is just a mere curiosity.
Even enterprising entities within the tiny Amiga marketplace have no plans to directly commercialise their licensed access to the 3.1 source.
Negative consequences? None.
Positive consequences? I've wanted access to the source for a very long time, and I have even approached Hyperion about licensing it. But there is very little I could have done in one year even if I had everything primed.
It's cool to see that some have been able to make improvements to their software by having access to the source.
