There are numerous tools already out there for parents to use to monitor and censor what their kids see online. Schools have been using it since the Internet came out and it’s only gotten more robust over the years. Not only that, but kids always figure out a way around this shit and will continue to do so until the end of time because that’s just what they do. The only thing this does is punish everyone and implement more surveillance. And since people are people and kids are kids, there will be workarounds within days even without a VPN.
