I'm not sure why limited invite events is now under so much scrutiny.
The size of the LIV fields is way down the list of grievances from what I've seen, and most of that focuses on the fact that for such small fields there is massive disparity of player skills, include those shooting huge numbers and collecting massive checks, which is not seen in other reputable fields for the PGATour, DP, Korn Ferry, etc..
Even the PGA Tour has been doing limited field stuff for decades like Jack and Arnie's events, in addition to the Majors with their various limiting qualifying criteria.
Golf like every other sport has always been about exceeding at one level to pass thru a gate to the next and I don't see why that should arbitrarily end.
