You can raise the cost of cheating so that cheating kids will get annoyed and go cheat in some other game or scroll TikTok or whatever. We're not exactly dealing with nation-states here.
Besides, sowing discontent is a tried and true propaganda strategy.
The question is: who coughs up the money for developing these cheats? Some of these, particularly the PCIe hardware rootkits, take a lot of money, time and skilled people to develop - and it is not too far fetched to assume that a nation state has been of assistance here.
Others openly flout their allegiance to Russia like the MIG-Switch developers, a ton of "bulletproof hosters" use Russian ASNs and/or are based in Russia, malware automatically disables itself when it detects indications of being in Russia... I can explain the latter away as "don't shit where you eat", but the others? There's no way there aren't direct links between the Russian government and the criminal actors. At the very least there must be some sort of "tacit approval".
Government officials and security researchers play videogames too, after all… sure, we’d hope they’d have good computer self defense. But it is a fishing expedition and all that.
