My take? Big Boi (Trump supporter) is broke.
He's leveraging Outkast trademarks to try and get money. This was done a few years ago with an EDM group called ATLiens. It was settled out of court, they still go by the name.
I hope Ovrkast has good lawyers.
Read a little more into this OutKast/Ovrkast lawsuit, and apparently they’re not only asking for a name change, but also all profits made under the name, punitive damages, and for all merchandise Ovrkast has produced to be destroyed. Too extreme
