In IX, Picard stops an Admiral who is breaking the Prime Directive... Insurrection... not so much.
The Prime Directive didn't apply. The Baku weren't natives or even truly a pre-warp culture.
...and yet Picard thought he had to go in there, right in the middle of the Dominion war, and screw around with this totally inane plot. At a time of war you have to pick and chose your efforts. For example, during WW2, if Grenada had been invaded by whom ever do you really think FDR would have diverted any of the WW2 effort, let alone the Flagship of the military, to assist..I doubt it....

However, the war was over and they was a cease fire. So Picard would have been free to do whatever without risk of damage. In fact he was diverted from a diplomatic mission unrelated to the dominion when he took the detour to the Bakuu.
Picard can do no wrong....
