It's not a matter of illegal, it's a matter of how much of a grift it is. Celebrating merch sales about your husband's death is just sociopath level.

It matters in the context of this movement trying to play like they gave a shit about this man for the sake of sympathy when even his own widow clearly cared about engagement and merchandise than his actual death.

Admittedly, not that newsworthy because most of the world has stopped thinking about him, but TPUSA is still rolling and still riding that martyrdom angle.
