I'm not surprised SO many people don't understand ASCAP.
They put the music up to be licensed.
It was licensed so that music can be played.
The campaign bought the license.
"The Foo Fighters" were paid under the agreements they signed that allows their music to be purchased, in a license form, and played in different venues for different events.
You can't put an item on the market to be sold, it's sold, and then sue someone because they bought something you put up for sale.
It is a deception, a lie, gaslighting, in its purest form.
