Is it really true that when casinos claim to protect players based on the idea of "responsible gambling", but in reality they are using this tool to shield themselves from gamblers legally? They claim that they have given the gamblers a chance not to become addict or lose money on their platform.
So now responsibility is shifted away from the platform and onto the individual. And in a hindsight, "Play responsibly" is somewhat design to be opposite, as it could encourage us to play more?
That depends on the person and how they can take it, whether looking into it as a warning or just as a casino shield or a way of gambling more, as you said. If I could place myself in that situation, I would take it as a warning and protection from gambling because I have nothing to do with the casino, regardless of whether they are winning, losing, or trapping gamblers. Gambling has both the possibility of winning and losing, and for that reason, I will adopt the slogan of the casino of responsible gambling, as it protects me.
