As a parent, I welcome these changes. When people say, "parent your kids," this is what I need to do that: an os-level setting that serves as a source of truth, a browser that reads it, and sites that require it.

If you don't like those things then use another distro or create your own, branch a browser, and create your own Internet. I welcome that. Until than, don't say the contradictory phrases of " parent your kids," and resist any of the infrastructure to actually accomplish that.
