Accusations of whataboutism are basically used to stop conversations because the accuser does not like where the conversation is going.

That's false. Whataboutism, in its traditional and non-negative sense, is the long-standing assurance of equal-enough application of the law as a defense against Bananaism.

See, I can make up truly stupid neologisms as well. But at least mine isn't an effort to subvert foundational democratic norms.

Whataboutism's necessity increases as the parties and potential charges under scrutiny are ever more alike.

The people most concerned about whataboutisms nowadays are usually just using it as a way to completely avoid self retrospection and shield themself from what they are accusing others of. Yes, sometimes it is a non sensical argument (when you bring up something completely unrelated), but it is a very very overused online buzzword now.
