As someone who has been to Cuba recently... the problem is restriction to internet. The government highly controls it. You can only access the internet with a special wifi card in a handful of designated wifi access points in each city. It's very expensive: $1 to $3 an hour, when the average monthly salary is $20 to $40. You can imagine the government will closely monitor activity, punish those who try to do anything against the state and shut down all websites promoting something like this.
