Pay to play is inherently anti competitive though. All cars that speed are fined, not just the “big” ones. It’s also a fact that all companies opening up their data would make things more competitive. Moats are inherently anti competitive.
Pay to play is a really broad term (just skim the wikipedia page) and describing it as 'inherently anticompetitive' isn't saying much. There are also plenty of political, social and business arrangements that are deliberately anticompetitive by wide agreements of various sorts.
