This one's hilarious Joshila. It was clear that the BCCI tried to get Pakistan barred from the World Cup in 2019 as per the article below.

So, in comparison, Mani's tweet is pretty sedate in comparison.
Ok, ok, so I won't use the tired tool of 'what-about-ism'. But Mani's argument is relevant. The Asia Cup is more important than the IPL on relative terms. The money generated from it is a difference maker to associate boards who get scraps from the ICC.
The BCCI, as is it's want and record, will prioritize the IPL in the September window, given that it's always looked out for No.1.
But, in doing so, it will demonstrate to ACC members it's lack of care for the development of the game in Asia. One can build it's bank balance in the short term or enhance it's reputation in the long term.
