I’d say: No.
They “played” a mining corporation, you “played” a big bad ransom dude choking people for money. so either they pay or they run or they hire someone to make you stop. Or at least ask around at veterans how to beat you. Even if they can’t beat you, they can blueball you by denying content until you go for someone else. Thats part of the game.
By bringing RL-issues into the game, trying to make you feel bad about some dude with a heart condition that may or may not really exist, they have crossed a line, not you. If that guy really existed, maybe he should have not played a competitive sandbox game which is known for the fact that the players have multiple ways to step on each others toes.
