It goes beyond just pointing out hypocrisy. This is a well known propaganda strategy called "Whataboutism." [1] It's unfortunately a tremendously effective smokescreen that divides the audience and shuts down meaningful debate.

There is some nuance, because I’ve also seen genuine discussion falsely labeled as whataboutism.

If the point in bringing up the hypocrisy is to end or distract the discussion, it is whataboutism. However, if the point is to compare two instances of a thing to make a point it’s fair game imo.
