You are right, Dubai is the most admirable place for cricket because when there is any risk in specified countries most of the countries will decide to conduct the cricket matches in Dubai and they will share the revenue, it has already happened many times in the history.
It is not just the revenue-sharing agreement and low chances of rain. The topmost advantage in playing cricket in the UAE is that they don't have to pay any entertainment tax or income tax there (UAE doesn't have any of these taxes). When the BCCI conducted IPL in UAE, they saved around 30% of the total amount in the form of tax waiver on ticket sales and GST. The players also benefitted, as they were excluded from personal income tax (which can be as high as 43% in India). And obviously playing in India means providing favors to the politicians and bureaucrats in the from of free tickets and dinners.
