As mastodon allows multiple threads, I'm going to go beside the point:
The historical whataboutism has a poor reputation due to us still being close to 1950s and affected by partisan rhetoric of the time, and we side with the USA.
That being said, USA's rhetoric hinged on the fact that USSR politbyro was technically responsible for everything, while USA had plausible deniability by working through companies and client states.
Which whataboutism tried to point out.
