Sometimes raiders are tasked with destroying the maximum tonnage of enemy cargo. In that case, yes, any info that they're in the area is highly counterproductive to their efforts.
But other times, at least hear on Earth, they're used to force an numerically superior enemy to disperse his forces to chase raisers all over the oceans. In that case, while you still don't want real-time info (radio) announcing you've just stopped or attacked a freighter having survivors turn up to report your attacks is helpful. (As long as you move out of the area first). Survivors add political pressure to stop the raiders, pushing the navy to divert and disperse more units for that task. And again by delayed reports of your actives, spread over as wide an area as possible, it again pushed up the number of units and resources needed to chase you.
Yes having to constantly move to new hunting grounds cuts down on the number of freighters you can attack, but it prolongs your mission and achieves the dispersal of units you're looking for.
We just don't know which of these 2 tasks the SLN is ordered to prioritize. But given the transit and message times its way less risky for them to dump crewman on a neutral planet than it would be for a raiding ship to drop them at a neutral port after the advent of underseas telegraph cables (much less radio)
There is one point that I (after reading quickly) don't see anyone having made is that PROFESSIONAL naval officers, especially commanding officers who have a couple of brain cells bouncing around between their ear, will realize that eventually there WILL be a reckoning if things don't go totally in the SLN's favor.
War Crimes trials or summary Courts Martial.
Even regular naval vessels which act like pirates and are identified will be treated like pirates either if taken in combat (and the senior officers survive) or afterward if there is a peace treaty or the SLN capitulates.
That hemp necktie can get mighty tight.
Commerce warfare has rules. Outright murder is outside those rules and whoever the offender is captured by may not always cross all the "I"s and dot all the "T"s in the ensuing legal proceedings. The RMN and RHN probably would observe all the legal niceties but would Erhwon or the various SDFs? (How long can you hold your breath? It's a long walk home without a skinsuit.)
