That's what comes with having a PGA tour license, its pathetic but i'm surprised its taken them this long. If ANGC have got all precious even about Magnolia then bollocks to them, not a great course imo anyway, iconic yes, brilliant...nah!
I don't think it has anything to do with having a PGA TOUR license, I think it has to do with a Tweet about the updated Augusta National course (and named literally that name) being "@'ed" to "themasters" Twitter page, showing a picture of the course. I think the wrong set of eyes finally saw it and set the legal works in motion. ANGC probably never even heard of The Golf Club 2019 until four days ago, when this tweet was posted.
