Some legitimately have an issue with professional athletes selling their services to business owned by a group with a history of questionable human rights actions.
The P.G.A. and all parties intimately tied to it, however, are simply concerned about their own product getting a bit watered down. It's nothing but self-interest, and anyone who disputes that from their side is lying. These players aren't under contract to play exclusively in P.G.A. events, so the only lever the P.G.A. has is public pressure via the human rights angle.
And yes, it's hypocritical. When these same people demand that the N.B.A. stop earning profit from China, I might listen to them.
