Whether or not that’s true at the moment (obviously, the status quo has changed because in 2020 UPlay changed to Ubisoft Connect, so the alleged incident happened years ago, and it’s alleged that Ubisoft were forced to stop selling something, so they wouldn’t still be selling it), the article specifically says:
Uplay featured a $15 USD Rainbow Six Siege Starter Pack, but this version was not available on Steam, making the cheapest option on Valve’s platform much more expensive.
The obvious way of parsing that is that it was the UPlay version of the game, but even if not, it’s generally not viable to sell Steam keys for things not available on Steam. The only time you can is when a game’s delisted but you’ve already generated keys for it, and then Valve can just wait for Ubisoft to run out rather than making the alleged threat.





There’s at least one company that does tweak (iirc used) airliner turbofans by taking the fan part off so they just have the turbojet (which is already tuned to mostly generate rotational energy to drive the fan turbine rather than produce thrust itself) and use that to spin a generator. Obviously, it’s a bit more complicated than that in reality, but there are quite a lot of old engines no longer certified for flight out of an abundance of caution but that still work fine, and a market for high-power generators that don’t need to be the pinnacle of efficiency (originally as backups just for occasional use, and now because of AI companies caring only about speed and not about cost).
