If some bitcoin critics are in government, there is nothing that can be done. But they like or not, a day is coming that more countries out of scanty that do not support bitcoin will support bitcoin and they will likely be among. Time will speak.
However, Kuwait is one of the 2nd richest Muslim countries. Despite this new policy I'm not sure it will create a backlash because it's not necessarily that bitcoin is of critical interest among the population. On the other hand I believe almost every citizen in Kuwait has achieved their financial freedom.
The important thing is that there are no dirty practices in the political system, I think their policies result from common sense than other corrupt countries, and rejecting bitcoin is not controversial at all.
