Do loot boxes lead to gambling addiction? If there is data on that topic, I'd like to see it.
They don't. Mental health issues lead to gambling addiction. Those exact same mental health issues lead to people "gambling" on loot boxes or gacha games (Genshin). And some developers even abuse that fact - mostly pay-to-win games and games with loot box items that alter gameplay in some way.
So, if we are to actually "think of the children" as geekmux suggests, then the correct option isn't to punish Valve for something they have little control over outside of banning trades or getting rid of the boxes altogether..
I'll just stop you right there since you just identified exactly what can be done as a quick fix to this. When they refuse to take away the loot boxes, you will then know exactly how deluded you are about clutching onto definition semantics while the gambling junkie in the corner itching for another spin tweaks and twitches on pure denial.
WHY do you think we don't allow 12 year olds throwing down chips on the tables in Vegas? Is it purely because "mental health", or is there just maybe another massively immature factor here? When we say WE must think of the children, WE refers to the fucking adults in the room. BECAUSE the children DON'T think. That's why we call them children.
And we should start remembering why we do without some excuse-peddler grabbing a dictionary and thesaurus to debate how we accommodate Greeds every marketing desire targeting ages 8 to 80.
