Well, now you see one, I am making it.

Your analogy with tangible goods doesn't work. Shoplifting, or stealing, could be a felony and is heavily frown upon morally. The risk of getting caught up is much higher, and the consequence is more serious.

I won't be angry about "thieves getting them for free" despite I paid for the TV, because I knew they will end up in jails eventually, if not already.

Piracy, while theoretically illegal, is almost never punished. It realistically has no risk. So there are a lot more people doing that than shoplifting. And yes, I feel salty when I paid full price for X game while someone is getting it free.

>What would the motivation for not wanting them to get it for free be, then? Unless you don't want people to get your works in the first place.

I only want my paid customers to get it, whoever doesn't pay doesn't deserve to get it. Pretty simple. I don't find it's hard to understand. Go ask any artist live with Patreon money how they feel about it.
