>How are the game companies supposed to determine that it adds negative value?

Look at their own/industry data of comparable games that have been published with or without protection. I worked in the game industry, for AAA studios it's a no brainer. Denuvo for a big title that sells millions of copies runs about high six or low seven figures in costs, so about 1-3% of the budget, whereas preventing piracy in the first 12 weeks meant something like a 10-20% increase (tens of millions) in sales.
