Paying customers are footing the bill for that anti-theft
The guy is making over $500k off someone else’s product with a couple days’ work. I’m no Tankie, but you don’t have to be a high schooler or a pothead to have a problem with capitalism’s more toxic extremes. People have been conditioned to forget this, but piracy is a counter-leverage to prevent product pricing from going out of control. Just look at the average prices of Switch games vs PC games. The harder it is to pirate a product, the further the price of that product is from a value consensus.
These types of anti-thefts tend to false-fire for the paying customers (who footed the bill). This is especially true because he builds his mods against a closed-source product that behaves in ways he cannot always predict. Published modding interfaces are never perfect.
