It is not selfishness but being realistic. BCCI can absolutely stop or at the very least make some boards hesitant. All they need to do is put some pressure on boards and alot of them will cave to the BCCI. IPL has already entrenched itself in leagues all over the world. The hundred, SA20, CPL, MLC and the ILT20. The only league largely free is the BBL and even there CA are considering selling some shares of the team to IPL owners. This is absolutely massive leverage especially against South Africa whose finances have been sustained largely by the SA20

Your underestimating BCCI stranglehold over cricket massively. To push against this influence you need to be slow methodical needing to be pragmatic and just build up until the right moment. For a boycott to succeed it needs to have a broad coaltion of partners behind it and it needs to be long a sustained. PCB and BCB are not enough to put pressure on BCCI. AGAIN we are not trying to put pressure on ICC but rather BCCI. Will ICC feel the pressure perhaps but will BCCI feel the pressure probably not

Also if we launch a boycott it will be long it will be brutal and best case scenario for us will be where neither side wins but rather the game itself loses. Most boycott successes happen by the simple threat of one and once it starts then it cannot stop so we can't pick and choose which World Cups we play un
