Gamblers from UK are the one who should worry because this report is coming out from UK OP did not mentioned in his article whose government implemented this rule, gamblers operator should worry too because they will have less profit and many will not play frequently than they used to be, UK people are to much into gambling that the government have to intervene, and this is not a good intervention.
There are two sides that will be affected actually.
1-Gambling operation is going to reduce their profit significantly. (bad for operators, bad or good for government)
2-Gamblers (bad or good),
bad for high roller gamblers, good for addicted gamblers.
well when that happens, the government will control the gambling place because in fact the government cannot control the gambling place, because it is a private business, in several gambling places in Las Vegas and others I see the government does not dare to do this.
