I'd actually be ok with this honestly. Prisoners are rarely given a bunch of stuff when they are placed in a cell.
I'm still also in favor of changing the system in another way. Being put in the Brig should be temporary, a reasonable timer to be a punishment and give room to try and talk out the issues. Two (2) or three (3) minutes for instance. Additionally it should work on a 3 strikes and your out system. So, Brig -> Brig -> Maroon (Kicked).
This would make it a little more of a hassle to just kick someone to help reduce the potential of trolling in reverse (there is no system with ones own crew that will be immune to trolling, but in this way to push someone out you're gonna need a good 4-6 minutes to do it). But this way those being trolled by their own crew in Open Crew have some recourse of protection. I'd rather air on the side of those being harassed by their own crews than be worried out the fringe instances of people letting you do full Voyages with them and then boot you before the cash out or when a friend of theirs joins (which is normally the fear with this, but I suspect that will be more rare than the kind of trolling that can be done now).
Again, no system is going to be perfect, but I think we can try and find some kind of reasonable middle ground.
Hell, I'd also be cool with making it so that if you kill a boarder on your ship, they go to the Brig rather than the Ferry to wait for respawn, granting the capturing crew some gold but allowing the opposing crew to bust them out early. This way it is an alternative respawn system that can reward defending your own ship successfully, and gives a reason for their to be a Brig on a Sloop still. Plays into the "taking hostages" gimmick of piracy without making it unbearable to the person captured (as at most they will be held up the same time they would be on the Ferry before being ported back to their own Ship). Doesn't even need to be a lot of Gold, say 50, and it can only be earned by killing another crew on your own ship.
Would make the Brig more interesting in general and give open crews some actual recourse against someone intent on just being a troll.
