Some call it a what-aboutism, although theres debate on whether its usually fallacious or not. There have been cases illustrated where using what-aboutisms is a proper logical counter, but most the time people just like to shout fallacy at each other so they dont have to think about the point they are making.
Oh hey look, a strawman!
While there is a logical fallacy here I don’t think it’s a straw man.
It’s some form of two wrongs make a right.
Nobody made the argument they were responding to, they made it themselves and then posted a picture “owning” it
That’s strawmanning

Whataboutism is a fallacy when it is used to justify a behavior instead of pointing out hypocrisy itself.
“It’s okay because you do it too” vs “You can’t claim moral superiority in this case because”
Thank you for the examples, thats a concise way to explain it.
