Every person who chooses piracy is someone who is already unwilling to pay so they have practically zero effect on the profits directly but at the same time every person who pirates and talks about games is someone who is spreading news about said content creating more potential customers which means in most cases passive income increase.
The thing is when you see people talking about piracy losses they are talking about "potential earning" and not "actual earning", it never crosses their mind that just like back in the early days of gaming a game without demo was a risk of money lost so people rather choose to not buy the product before they heard from someone its good or tried it out elsewhere.
Just ask yourself, how many games would you have bought compared to all that you pirated if you wouldnt have access to piracy? My list would be pretty damm small, especially cosidering that i bought several games i pirated because the devs deserve that cash.
