Attitude of big-3 specially India is very arrogant, as they have rules like no indian player will play any foreign leagues, no Pakistani player can play IPL and what you mentioned (not sending team to Asian games). More sad is role of ICC in such situations as it merely has no authority to solve things when there is conflict. Do you ever wonder where are teams of kenya, Zimbabwe?
Here you are right Big-3 is main problem in ICC and cricket's better future specially Indian are doing dirty politics after introduction of IPL and having huge funds in their pockets.
But here concern is not IPL, and we are not talking why they are not allowing their players for other leagues and now allowing Pakistani cricketers in their league here is concern these all boards need to do some worth with ICC for having better structure and other facilities in countries where we can do some good for this game and youths can join this as professional cricketer which is increase its popularity, and we will be able to have some more good and quality teams in this frame.
