I wonder if the parent company counts each persons signup as a separate customer across the different brands? Say if you nave got an account at videoslots and one at Mr vegas are you classed as 2 customers. This could really inflate a companies value when it can state it has 8 million customers when the real count would be 4 million. I.e. similar to the reason why Elon musk pulled out of the twitter deal as the 'customer' count was overinflated.
