Minecraft (Mojang/Microsoft) have also made it clear that with them moving from OpenGL to Vulcan they're maintaining the ability for Minecraft to run on Mac as well as Windows/Linux, which is fantastic.
My bet is that the real different lies in mobile devices - iPads/tablets and phones are something that kids have more access to than laptops or desktops, and lots of people don't bother with parental controls.
Roblox is getting pretty bad though with age verification, and they will NOT help recover a lost/hacked account no matter how much money was spent on it. 5 year account, likely thousands of dollars in robux spent on it, kid clicked a bad link and it's gone. Roblox just responds they can't help, even though the original email address was verified, and used 2 factor auth through its history. They used to be helpful, they don't care anymore.
