Counter-Strike especially has a pretty nasty gambling scene that Valve refuses to control, even though its only possible because of their marketplace and APIs.
I agree CS is icky re: skins and gambling. But to say “refuses to control” is disingenuous. They’ve done many things to curtail gambling, like preventing tourneys from displaying gambling sponsors and adding trade restrictions that hampered bot activity. Valve is between a rock and a hard place here- they recognize gambling is a net negative on the value of their game (hence the curtailing and remonetization efforts). Remember, valve didn’t create skin trading with the expectation of third party gambling, so this is something unprecedented they’ve had to figure out as they go. Despite its drawbacks, the gambling market has some positives that valve can’t ignore. It creates liquidity and demand for the skins. People who pay hundreds of dollars for skins hate to see their value plummet. So if valve nuked gambling today, it would upset a lot of folks. I think valve has done a phenomenal job balancing their business needs with the social obligations with the players.
They knowingly profit from gamblers if you will but gamblers are going to gamble.
The gamblers were offered e-sport or gambling and they chose the latter.
You could use Robinhood to build up a growth portfolio starting from a handful of dollars or you could use it to buy 0DTE OTM options on credit. Guess which one the gamblers chose.
