There is now an education version. And Minecraft never really said it was 4 kids. It’s your choice to stay and get bullied or join another server. So Minecraft is good and that’s that. Mojang can't see everyone’s chat at th same time. That’s the servers creators job to ban rude or inappropriate people.
It has no chat restrictions at all! And guess who gets picked on even after having an over the top moderation system? Roblox. Minecraft is considered completely fine with no chat restrictions, Enabling anyone to say anything which easily lets your you get bullied, Or let’s you bully other people! I bet you could even say some incredibly rude words. And roblox is constantly being picked on by the news, By online safety websites by parents yet Minecraft just gets away Scot free. I bet soon Minecraft servers will be madhouses with people swearing and harassing each other
