That's been my theory as well, that the ultimate victim of Photoshop piracy in the 90s/00s was Paint Shop Pro. Adobe didn't seem to care, professionals still needed their properly licensed copy at Adobe's prices, and students who learn with pirated Photoshop might become actual professionals with paid licenses in the future.
But at $0 vs $0, Paint Shop Pro was a lot less appealing that it would have been at $99 vs $399 or whatever Photoshop used to cost.
