Gambling companies being licensed actually helped in checking scams because the process of obtaining the license avails the authorities the chance to know the faces behind the platform and in case of any issues, attempts can be made to bring them to the table. Unlike unlicensed casinos, the operators can do what they like and hide their identity completely which is dangerous on the long run.
However, from the side of the authorities, they are more interested in the taxes and levies they will get from these casinos and not really because they care about anyone. The whole reason for the crackdown on gambling will mot be far from taxes and levies.
