>Ralph Langner, a researcher who conducted an in-depth analysis of Stuxnet after the malware’s existence came to light, noted that “a water pump cannot carry a copy of Stuxnet”.
In his Xitter post he also says the infiltration timeline doesn't match his analysis.

who to believe ?
Anyways, from this perspective, even back then, the analysis was pretty thorough:
If you're not familiar with pinyin, do you still read that X as making an "Sh" sound, as in Xi Jinping?
Well, that's all the proof I needed — a twitter post with no further information.
Obviously he may be right as he is a researcher and most likely actually did the research, but an non-sourced definitive statement on social media is not what I consider "proof".
The more hard to believe part is that a lot of electric equipment like water pumps have very simple software running on them, which might only be controlled by some messages on a serial bus that sends certain commands. To use that as a vector you would need the software to have very specific vulnerabilities.
Hence, I doubt they employed people to promote piracy on the PS2.
