I highly recommend to people that don't understand why some are so pissed off with this to read Joey D'Urso's reporting on this issue over the past 6 months in the Athletic. Here's the first special report he did, with the main headlines below;
So it's actually quite likely the club didn't dig very deeply into this new sponsor, because they don't care to know more. They have a white label licence, that's enough for them, it doesn't matter that all it takes is a service fee to a middle man to get one.
It also mentions in the article that some clubs don't allow their best players to appear in advertising for these companies, only the older, less valuable ones, so clearly the clubs recognise it's a bit dodgy.
I think gambling in football on it's own is a big issue that needs to be taken seriously, I'm tired of every match having 10 minutes before, after and at half time shouting at me "BET, BET, BET! Please gamble responsibly. When the FUN stops, stop.". But these Asian companies using white label middlemen really take the cake, and for me it's disappointing that Villa got rid of one to go straight to another. At least we don't have one as our main sponsor anymore.
