I wouldn't take any publisher's opinion seriously. It's been proven that music piracy is _positively_ correlated with sales, yet the RIAA is still trying to stop youtube-dl from existing. I have to assume these pencil pushers in the game industry are equally ignorant, until hard data proves otherwise.

Which makes sense, things that sell well also are more likely to be pirated. Has it been shown that piracy causes sales to increase? I've looked around but I haven't found anything reliable.
There was one (not replicated) study suggesting that people who consumed more music tended to pirate more, but that's a correlation not a causation, and it doesn't follow that they would not have purchased or subscribed to even more music if the piracy option had not been available.
doesn't matter if they are right or wrong, especially when you are asking for their money. It may be a business, but it's till run by flawed humans whose irrational decisions will affect creators. So this perspective is important for a developer to know before pitching a platform.
