Earlier quoted context omitted.
People get busy... I was building my startup around that time period, and didn't really play games for ~5 years. Why would I reward a company that already stole from me with another purchase?
If I was too busy building my startup while my Starbucks Frappuccino melted, Starbucks didn’t “steal from me.” I understand living by your principles but in my experience, the process of running a pirated server/clients is enough of a pain that it’s not worth $30 of anyone’s time, even if it’s the second time you’ve had to pay it in the span of multiple decades.
Edit: Your edit clarifies things a bit. Eh, I got my start in software development working on an emulated Lineage 2 server ~20 years ago, and eventually building my own server from the ground up which extended the game in ways that the normal servers / client didn't support. I think tinkering is fine if that's what interests you.
I don't spend much time these days with games (compared to the past) regardless.
