To me it is censorship.

If you are a small child it is indeed up to your parents to censor adult content and I am all for that. Kids will be upset but that is part of growing up. When the parents believe the kids are emotionally ready for adult content then I am sure they will get parental controls disabled. Even if that should not come to pass the kids once they are teens will bypass it anyway.

If you are an adult and your followers are adults then this does not really apply to you or your device. This would only hurt groomers, most of whom use video games for that purpose.
