Yeah, if they lay low & bide their time for at least a generation, working their way to zoos and native populations without humans finding out, they might have a chance... in another fifty years, maybe. But going straight from the lab to La Revolucion can't end well for them without a heapin' helpin' of writers' conveniences.
Actually, now that I think about it, that could totally work, if handled right. A short, bloody, but small and quickly squashed coup that leaves only a tiny handful of uplifts still alive on the outside, who then spend years/decades making their way in hiding out to the zoos and jungles, building up a secret culture based on refugee solidarity, before eventually witnessing their "evil" persecutors self destruct, leaving the "peaceful" apes to inherit the land. Ceaser tries to be John Conner, but ends up being Moses instead.
