Well that nicely sums up your point of view. So you'll do anything to gain that experience, even if it's denying someone a paid flying position?
CAP is a volunteer service, so we're not talking about that. However, logging your 135 freight flights as "flight time" may get you into some hot water with future employers. You had no official training or type rating and were not a required crew member. In my book, I wouldn't look at that time as being the "experience" you claim it to be. Like you said, you were just riding along...... Make sure to get a real job with real responsibilities before you claim that you have all the necessary CRM and IFR skills you are so desperate to obtain.
In this business, you either stand for your principles, or you get walked all over.
