I'm not going to take sides here, since I believe the entire dynamic is broken.
As a Bounty Hunter, I never had someone I couldn't pull from SC. Hunting in a Viper, Cobra, or even an Eagle was pretty easy. If it was a freighter, they basically had no chance in combat. I'm not a great pilot, but it was heavily balanced in my favor. They either ran or they died.
As a Trader, I find the situation is the same. I sure as hell can't fight them... they outgun and out-maneuver me. The only interdictions I can shake off are NPC interdictions... when a player interdicts me, I can be parked on the blue circle for 15 seconds straight, at full throttle, and I'm losing the minigame. I couldn't win the mini-game, and I couldn't win in actual combat, so I dumped the 2 million into top-grade thrusters and power distributors, and I run... disable flight assist, chain boost, chaff, SC when off cooldown. The only ships that keep up are Cobras and Vipers that are willing to do the same. It's a technique that both can employ and master, but it's not always easy.
If they're persistent, it ends up being a stalemate. I had one CMDR follow me around for almost an hour one night. I would hop back into SC, drop back out with no target, wait a little bit hoping he would be gone. He wasn't. He followed to neighboring systems, well off the rare loop. Neither of us got anything done that night... he got no loot, I got no trading done. A complete waste for both of us.
I play Open because playing Solo feels cheap. I don't like these interactions, but pirates are part of this world; they're part of the game content. I'll never drop connection, or use network tricks to escape. If I log off for the night, I do so in a station where I've escaped to and hidden, just as a real pilot would. The frustration at that point is the same for both of us... we've both failed at our tasks for the evening, and our game time is basically done.
The entire dynamic feels off to me. For a trader, that could be hours or days of work lost, depending on how much time they have available to invest in the game. (I'll leave the discussion of the ridiculous time investment expectations of this game for another thread.) The best case situation for the pirate is dropped cargo, which they could have retrieved themselves from the neighboring system in a few minutes. The worst case is lost money from spent ammo, and nothing to show for it. The best case for the trader is escape with the cargo, and the worst case is immense loss of progress. It's just not a good interaction for either side, and that's really what needs to be addressed.
Anyway, sorry for the wall of text. I'm sure it'll get lost in the thread rage, but I wanted to toss it out there in case someone had similar thoughts.
