This is a good point, governments know very well that they make the rules of the game so they can threat whole industries with the severe actions against them and they know they can use any excuse that they want as people are going to believe them in order to officially raise them the taxes that they need to pay or they can do this and force them to pay an amount of money under the table that can serve for other politicians of the same political party to try to gain positions of power, this is corruption but it happens all over the world.
Setting bans in betting adds was just one of the way of the government to prevent a drastic effect of gambling into its constituents especially to lessen the curiosity of the child that could possible watch the adds. Eliminating the possible gambling addiction is impossible because a gambler will always find a way to engaged in gambling even if the government prohibited it. I see the positive side of this implementation for the sake of those vulnerable people but in gambling sector this may greatly affect the exposure of the establishments and business.
