That's true by definition isn't it? Piracy (Internet piracy, since that's the context) is copyright infringement, not theft.
Since you talk about game developers, just today was "Hollow Knight: Silksong" released, a game with no DRM (which means it will be on every pirate site the minute it releases, something that was known beforehand), and had just a few hours later over half a million concurrent players on Steam, one of the many storefronts where the game is available.
No industry has ever been killed by piracy, not even close, and the cases of musicians, authors, and game developers who have attributed piracy to their success keeps piling up. I really don't get why people who in other aspects of life try to look at the facts of things keep arguing so fervently about something proven to be, at best, a net positive and, at worst, a way for more people to enjoy arts and entertainment that they would never had otherwise.
If you don't get money for your works, you might be unlucky, or you might just not be good enough to make what people want [to pay for]. As a game developer myself, that's certainly my case. I hope to one day make something so many people care about, that they go out of their way to pirate it, because statistically that means I'd sell a lot of copies.
And I'm not arguing it's killing the industry. Shoplifting exists today but brick and mortar isn't dead (Well, it is dying but that's because of online shopping). But stores would see a little less profit due to shop lifting. Very similar to piracy.
It is stealing, and using an out dated definition to try and paint it as anything else is a wild take.
I hope you do make it as a developer one day, and create a hit game, and you have some telemetry showing 10000 people playing and check your Sales to see 200 copies sold and you tell me if you think you haven't been robbed.
