I was reading about that interview, and it amazes me that he could say all that. I think he started to realize the hole he was digging, because he eventually started talking about just how few underage programmers they actually have.
IMO, you just can't mix for-profit with child labor. I don't care how much some of the children get out of it.
But then to find out they only pay out like 30% of the earnings? Outrageous. There's no way you can say that isn't exploitative, IMO. People are already railing against Steam/Google/Apple/etc for only taking 30%, and Roblox is over twice as bad for adults. Doing it to kids is just so incredibly wrong.
For anyone who is unfamiliar with these and wants a more in depth look at how Roblox is definitely exploiting kids (from 2 years ago, so you know it's somehow been made worse since)
On Google Chrome the this basic functionality is hidden/unavailable because Google is an advertisement company and, of course, they don't like for you being too comfy into avoid their ads. But still can happen over Chrome too
Regardless of how you feel about how the Roblox platform works and if it is or isn't exploiting child labour you ought to think that this would be something that corporate will make sure everyone refrains from saying it or entertaining the idea when talking about the platform because well... it makes it look bad.
