I personally understood that point as well. But the point I am making is, the developer or publisher is responsible, not Valve. The price recommendation tool by Valve is just a help, not an enforcement. Before this tool, publishers did the pricing themselves and the prices "were wrong" too.
What I mean is, as an analogy, if programmers use Ai tools like ChatGPT and produce bad code, then the company behind ChatGPT gets attacked instead the programmer who is responsible. Yes, to a degree both are at fault, but its the publishers / programmers fault of trusting it blindly.
