The IMG and the Corsairs were never neutral or allies by favor of canon. They've never even been strenuously neutral. On the short list of groups the IMG hates (about 6 groups) the Outcasts and Corsairs stand shoulder to shoulder.
The IMG supports and works with the Hessians. Not exactly fertile grounds for Corsair <3
The CR and the Corsairs were buddies back in 4.84 and earlier due to various diplomatic hodge podge like enemy of enemy is my source of cids and so on.
So! To reiterate!
The IMG murdersauce hates Corsairs.
The Corsairs murdersauve hate IMG.
