I don't agree that this is what happened. Let's recall that the ban came in about February 2022, and the World Games were only four months away. WCBS, more than likely, felt that anything that could have been interpreted as defiant at that moment in time could possibly endanger the inclusion of pool, snooker and carom in the World Games, all of which generate quite a lot of money for the national federations. WPA, pool's delegate to the WCBS, really had no choice but to follow the WCBS in this matter.
The fact that the decision to lift the ban came during a WCBS board meeting held during the World Games is noteworthy.
No doubt I'm being a bit speculative in this post, but I can't fault WPA for complying with the WCBS decision on the Russian ban, and I'm not buying that they misunderstood IOC guidance. I suspect they just took the path of least resistance.
Where I agree with you, however, is that once WCBS/WPA see that the recently proposed ban is bad for business, they'll likely backtrack. We shall see.
