I can't remember all the details, but isn't this similar to the story about chinese 8ball in Europe in 2019?
JOY wanted to launch a Chinese 8ball EuroTour series and the EPBF threatened to ban all players, who would participate in these tournaments, from all European pool related events?
This clash occurred under my radar, and it's very similar to what's going on in golf. In golf, numerous PGA players asked, unsuccessfully, for a waiver to play in the inaugural LIV golf tour event.
Based on what you've said, the EPBF in 2019 was, in essence, announcing in advance that no waivers to play in Europe-based Chinese 8-ball events would be granted, and that those who chose to play Chinese 8-ball in Europe would lose their eligibility to compete in EPBF events.
By putting JOY on alert, it seems, based on what you've suggested, that EPBF's strategy obstructed that business venture. Still, in the case of LIV golf, the venture went forward despite the fact that the PGA had denied several of its top players the waivers requested. Many top players made it clear they'd play the LIV golf event despite having failed to attain the requested waiver, knowing they would surely be disciplined severely. Some of them, such as Kevin Na, opted to resign from the PGA tour.
On the other hand, the comparison of what happened with JOY and what happened with the 2006 IPT doesn't really work. That's because, in most cases, players didn't even ask for a waiver and organizations like BCA, WPBA, UPA, for the most part, chose not to kick up a stink over such actions. I think these organizations took the view that they could coexist with the IPT, which was only scheduled to play for about four weeks in the entire calendar year.
It's all very tricky, but whether it's the pool business, the golf business or any other business, executives go to great lengths to defend their market positions, and their means of doing so isn't always pretty.
