CUPS was so far licensed under what Debian nicknamed as "GPL-2.0 with AOSDL 
exception"  [0] :

Is Apple going with "pristine" Apache License 2.0 [1] without further 
exceptions? This is going to make CUPS incompatible with GPL-2-only software 
[2,3]. My understanding it that it doesn't affect dynamic-linking situations 
(both software that CUPS needs, or software that need libcups*), aka not a 
concern for distributors, but are there other potential impacts of this 
license change that I'm missing ?
