You could argue that PvE piracy is harder than PvP. I mean, in PvP either they submit and give you something, you try and steal it while they run with hatch breakers or disable them, or kill them.
PvE they never submit, you have to get them to stop (which means taking out PP ideally, thrusters still lets their PDTs and other weapons work), without making it go boom, then it can take minutes of manouvering to get in front on them to bump stop them, and anything above mostly harmless can do a reboot/repair, and you're back to square one.
After FD made the changes to PP so they don't come to a stop and allowed NPCs to reboot repair (high ranking NPCs do it almost immediately), it really turned me off bothering with PvE piracy. It used to be fun, now its just a pain, unless you get lucky and find a harmless/mostly harmless target with a nice load.
