Parental Controls are DRM. They&#x27;re precisely the same problem statement and software solution: You want to turn general-purpose computing into devices that hide their capabilities from the user, selectively.

Even before then, the filters had not been 100%; I know by anecdote that I had seen some seriously deranged pornography before the filters completely dropped, and I really just wasn&#x27;t interested.
