Pros and Cons of Copyleft

From your perspective as a programmer, what are some of the pros and cons of releasing open-source hobby projects under permissive vs. copyleft licenses?

Does software that uses media under a Creative Commons Share Alike license need to be distributed under a copyleft software license?

I was wondering if the Creative Commons Attribution-Share Alike licenses expects software that uses it to be distributed under a copyleft software license.

I can't and don't want to use GPL since I use some libraries which are basically open source, but incompatible with the GPL. I thought about using LGPL or MPL/CDDL.

Can I incorporate GPL-licensed code into an out-proc COM server and use that server from my proprietary program?

After reading this paragraph in GPL FAQ I feel confused. That paragraph says that a proprietary program can use a GPL-licensed program via aggregation - as a separate program.
