It doesn't really make much sense from a $ perspective and really only serves as a lesser (and rapidly diminishing) halo effect for the rest of the brand. Logic is one of those programs that keeps people on Macs. I'm sure I don't need to explain this to a Logic owner but audio engineering and production was strictly a Mac-only affair in the past and that has rapidly changed over the past decade. Macs have gotten increasingly difficult to work with due to constant OS updates breaking everything and have only gotten more expensive with less options for actual professional users who need real I/Os. Keeping Logic fresh is important to keep people from switching as everything else they do on a more macro level is pushing people in that direction.

Someone somewhere in Apple decided that holding onto this market was worth it for probably solely the halo effect. I can't think of any other reason and makes no sense from a strictly financial perspective.
