A pardon can be pre-emptively issued; there are many examples of this. Since there is no utility, this project is dead as maximum value has already been extracted from it. Trying to get more would either be an exceedingly diminishing return or getting blood from a turnip. Remember, ultimately tokens are spent and this one has already been spent as well as played, i.e, used up.
Lawsuit is against Kelsier Venture and it cited many meme coins other than the infamous $LIBRA and $MELANIA so I doubt there would be any pardon.
In my opinion $MELANIA is just a small piece of the entire lawsuit, the lawsuit itself involves many thing non Trump related.
Have you been paying attention of whom has he been pardoning in the past? Everyone praising him and giving him money seems to get a pass sooner or later. And this is definitely one of them. Not pardoning them would imply that he has been scamming his followers and doing business with criminals (like he has).
There's however going to be a scape goat for all this and it's probably something completely mental again, like trans people, antifa, or woke that caused these rug pulls.
