Carrousel7956 While it is designed for security first and foremost, it is also designed for privacy and it absolutely makes anonymity far easier than other devices.
I don't disagree with anything else you have said though. And it is Roblox's responsibility full stop, but they know what goes on inside their game and the fact they are explicitly allowing Graphene and potentially other ROMs to work when the targeted age range of their user base is highly unlikely to be using custom ROMs or GrapheneOS is what makes me very uncomfortable. It's highly suspect to me and shady as hell.
