Yes, let’s blame the f2p game dev when there are literally streamers pumping fake platforms, doing fake wins, marketing gambling sites at kids. Valve did that
It's Valve that created the loot box mechanics (i.e. gambling). That's the foundation on what everything is built. And even without the adjacent ecosystem, it's still Valve that's exploiting children by introducing gambling to them.
I have no skin the game, literally or figuratively (buying some 2d sprites for a virtual weapon is childish and pathetic from grown up man point of view and kids should spend 0 time in such game... either buy a real gun, get into ie paintball for the kick of the hunt or find something else that feels amazing and doesnt involve sitting on your introvert ass, worsening isolation and mental issues), but - your argument is very weak whataboutism, and ignoring who introduced it all, to weakest members of society to prey on addictivity of it all.
Pathetic all around, imagine I am giving you a minus I cant give, and expecting better from you next time.
