Isn't there evidence/speculation that some of the chips that were sold to MegaSpeed "somehow" ended up in Russian drones in Ukraine? However they for there the take away is Nvidia chips were found in Russian drones, how were they procured?

I was not aware that NVidia chips were found in some Russian drones. I can confirm that accusation with some light Googling that shows reliable news sources. Those chips aren't very special. You can buy dev kits on Amazon.com[1]. So, I assume someone is buying 1000s in a friendly country, then smuggling them to Russia.
