I'm a millenial but even I'm not this naive. Youtube kids is full of nsfw, roblox is full of nsfw and probably half the stuff you sit your kid in front of is unmoderated. There doesn't exist "kid friendly" spaces like the old days. It's not financially viable because its hard to moderate so most "kid friendly" apps are in fact not kid friendly. Even stuff like disney can be bypassed. Itch.io is literally the wild west of the internet, it's like sitting a kid in front of OG newgrounds if you want a comparison you can understand.
