A couple of problems with your post.
1. You have to be in radio contact in Class C, and you must accept those vectors/altitudes. But its only 10nm in diameter. You don't have to participate outside of it. When I arrived VFR at Laughlin a few trips ago, I got radio contact at about 12 nm from the field, with them acknowledging my callsign. As I blew inside of 10nm, they got audibly agitated. When I landed, I was told to contact the TRACON. Long story short, I dared them to file a violation on me. "Bring it" I told them. They backed off and said they "would let it go this time"
2. When you depart the Class C, call "terminate" and your flight following is done. You can go through the MOA all day long and not talk to a soul. But if you are VFR with flight following, you still have to accept controllers instructions. Don't want to follow them? Ball's in your court.
Caveat: If you have an incident, and you were not getting flight following, expect to have your nuts crushed.
