It’s not whataboutism when you’re comparing the exact same actions and the two things can be substituted for each other.

Whataboutism is “how dare you complain about our gulags when you treat your black people like slaves.” It is not “our system kills people but it kills fewer people than what we currently have.” Especially when killing people is a result of being on the bleeding edge of what’s possible rather than being a deliberate choice to hurt people.
