What I think the beautiful meaning behind this is...
Losing friends or followers can happen in life, friends come and go, and sometimes you don't need friends to be happy. But if you follow other people and believe their lies and stick to their opinion even though you might not agree with their opinion, you are under their control. Not only you are under their control, but you pretend to be something else by agreeing to these opinions and pretending you agree. Never always follow other people, you don't need to be the follower. Be the leader of your own tribe.

B. I assume because none of the other words would make sense in the sentence when it has the word of. XD
