And it’s no illness but a personal trait, but as you feel attacked, feel free to be into the face.
I’ve never seen people leaving EVE because of PI, but I’ve seen plenty of players leaving their planets unattended after a while. There is no penalty on not doing PI.
For it’s a game, most players do what they want to and try different ways. I do not claim everbody should like PI, but so you can’t claim nobody likes it.
My advice to new players: Just try it after some months, if you like industry, after 2 weeks of skilling you are skilled enough to get a feeling, and as soon as you think it’s boring, leave PI. There’s no pressure, and if there is, you may be in the wrong corp.
PI is a typical job for an Alt, so normally your main character is a hero and after you had some adventures and learned about EVE, you may set up a PI character to earn some easy money.
