This is certainly true if the trader obliges and drops the cargo with no shots being fired.Right now there is little profit in piracy and also surprising little danger due to very few consequences.
Hell, loitering in a station is more dangerous.
I think the real point I was trying to make, however, is that the danger and profit is somewhat irrelevant. Pirates largely do it for fun and interaction and have continued even when they barely break even after interdiction repairs.
If people are saying pirating should be hard and unprofitable, well it already is.
If people are saying they don't want pirates in the game at all, well I don't think removing abandoned for them would achieve this.
Maybe Frontier could add a third cargo ejection option "Abandoned under duress" which would alert the police?
