Why does Roblox get blamed for things other games (like Minecraft) don’t?

Hello, as someone whose only interaction with Roblox was when I was an 8-year-old, I've recently been met with negative press against Roblox, where the firm seems to get blamed for a lot of problems (safety, moderation) in a way that other huge platforms like Minecraft don’t get blamed as publicly, even when similar issues exist.

So what makes it different?
