But doesn't all of it kind of fall under the same umbrella? A grudge doesn't maybe, & that could certainly be a part of it. There's plenty of reasons for people to have grudges against Picard & Co. in general, & the Borg stuff is certainly a tool they could use to effect some retaliation, but apart from that, what's the difference between doubts about Picard's mental state or allegiances, versus open manipulation, as far as they're concerned?
I gather it's the remote control aspect. If Picard's putative traitorous leaning and intent was his own doing, Starfleet could dig it out of him with procedures mental and physical, and then definitively declare him cleared, cured, or forever incurable and untrustworthy. But if he is physically and mentally fine till the moment the Collective makes contact... That's the worst sort of sleeper agent imaginable, because they
know he is one, yet they don't; they can never pin anything on him in court.
We've never seen other "Contact mode" moments until the 1st Contact events, & it's fair to assume that Starfleet mightn't even be privy to the ones he has had anyhow, as a basis for their suspicions, (You'd want to keep that to yourself) but that doesn't mean there hasn't been others, & it isn't really the likely basis for any suspicions anyhow.
He's damned either way. If he has been caught contacting and Starfleet can't figure out how and why it happens physically (Beverly did seem to believe in the successful extraction of the nanoprobes), the only proof they can get is interrogation of memories, telepathically or otherwise. And we know that for some unknown reason, this is not eligible in court, or at least sees zero use. (Even the psychotricorder is either a bluff, or then merely replays the person's psychopathological history rather than his memories.) A known but untouchable sleeper agent is not going to enjoy much of a career, even if he were the first to admit that such treatment would only be fair and logical. But if previous contact can be proven... Spies and traitors still are treated fairly conventionally, such as in "Drumhead" before the Spanish inquisition mode kicks in.
But I want to believe in ST:FC having been the, uh, first contact, seeing how it shocks Picard here, vs. his relative calm throughout the various TNG episodes and, say, "The Emissary". So I agree Starfleet suspects him on some other, far more general basis, and thus isn't able to take more effective containment measures in ST:FC.
Besides, it's his ship. You kind of have to shelve the whole ship, if you're shelving the captain...
Huh? No, it's not his ship. It's very much Starfleet's, and Starfleet can always send him fly a desk somewhere, or give him a science vessel that won't be missed in any big anti-Borg fights. This they could do while keeping the reasons implicit, or by stating them at his face with appropriate spittle. Few organizations are known for their timidity in HR matters, and the UFP's de facto combat arm shouldn't be one of those.
(That they don't in ST:FC only goes to show that Starfleet distrusts the whole ensemble cast, and considers the worthless E-E a fitting gaol for them for the duration of anti-Borg action. Although why nobody sabotaged the warp engines, nor was given orders to stun the top officers at the crucial hour, remains unexplained. Might be Nechayev turned that down when Raner proposed it, or vice versa.)
