The rebellion isn't fake... just Bosch is an operative and, in the end, would have cooperated with the GTVA (his deployers!) to lure the rebel fleet into a trap. He was just an aid to find the rebellious people.
I seriously doubt this from his monologues.
Why? I guess that the GTA (and
not GTVA) wants to ally with the Shivans against the Vasudans (by the way, the reason behind the SOC mission /Dive, dive dive!/ was that they tried to find Bosch).
Monologue 1: Nothing against the GTA.
No. 2: He has enemies, that's all. Calls his own rebellion an "army of stupid cattle". He states that "...my rebellion is about my love for humanity and not my hatred of Vasudans" - THUS he tries to help the Terran-Shivan alliance against the Vasudans.
"...and soon the alliance will learn the method behind my madness." <- This is a debatable(?) sentence, but I can't say that this breaks everything.
No. 3: Nothing again. He mentions that whether this ruse was useful or not (Fool's Crusade).
No. 4: He is happy that he achieved his goals. Tho he didn't expect that he'll be carried away.
Fact list will come soon!
