For what it's worth
Not much really since those countries are unrepresentative of the Muslim world
Black holes: Tunisia, Egypt, Saudi Arabia, Iran, Turkmenistan, Uzbekistan, Heavy Surveillance: Syria, Libya, Yemen,Bahrain, UAE, Malaysia, Tajikistan. Fair points about Kosovo and Bosnia, but I don't know what you mean by 'unrepresentative' with respect to the previously listed countries. If by 'major' Muslim countries you mean the ones that make it to the news in the West, then fair enough, they are very restrictive, but if you look at the religious values espoused by the inhabitants of these countries and try come up with which ones are 'representative', you would have to exclude Saudi Arabia and Iran and Bahrain since they follow minority sects and there are wide discrepencies between their beliefs and those of the rest of the Muslim world. Most of the other countries attempt to restrict religious practice in addition to the internet; In Libya and Egypt the type of religion practiced by the people may well be representative of the rest of the Muslim world, but in Libya the government is known to suppress traditional religious scholarship, similar stories in Egypt and Syria, where religious organisations are under heavy surveillance eg all congregations have to register and sermons have to be approved. The Turkic countries are very secularised; beards were forbidden in Turkmenistan, though I think they may have recently lifted that, and most Muslims there do not regularly attend mosques. Uzbekistan is similar in the level of religious practice of its population. In Tajikistan girls in government schools are forbidden from wearing headscarves, and many Mosques have been taken down or converted to other types of buildings. In Tunisia the government restricts the wearing of headscarves by women in public office, and discourages it among the general population. I think a lot of those countries restrict the internet for similar reasons to China; mainly to control the news that gets to their people and cover up injustices by the government.
