Maybe, but those who hate LIV would still hate LIV because it is a competitor to the PGA Tour. Both sides of this are disingenuous about the motivation/reasoning behind their arguments. The Tour hates LIV because it is a competitor to the Tour, and the LIV guys joined for money.
Guys like Rory, IMO, are just as disingenuous as guys like Phil. Rory might have more of a genuine personal connection with the Tour, its history, etc., than guys who joined LIV, but Rory hates LIV because it threatens to make what he has achieved (and will achieve in the future) on the Tour look less impressive if a bunch of good players continue to defect. It is why Tiger is so involved now as well; even though LIV didn't exist when he was in his prime, having the Tour where he achieved everything that he achieved disintegrate would look bad.
For the rest of Rory's career, I think he fears a Dr. J in the ABA-type of thing, although in reverse. Dr. J went from a league perceived to be inferior to one perceived to be superior, but Rory potentially is going from the superior league to one that isn't as superior as it used to be. He doesn't want a "Well, just how impressive was Rory's PGA Tour career once LIV came around?" debate.
