Im in a similar boat, at this stage I think a lot of people who have a tiny amount of knowledge about how the Internet works feel the same.
Labour seem to be marketing this to those who dont know what a VPN is, but that number is small and getting smaller.
11 year olds are taught what VPNs are in class.
The young children who could potentially stumble across harmful content are far more likely to come across this material on YouTube, twitch, or online gaming. There are hundreds of example of 'tasteful pron' on these platforms, and sex work camouflaged as art. Then there are the soft pron game channels.
My brother not recently subscribed to 3 twitch streamers, he's 12 and all his friends were playing online when one of them began a conversation with a streamer sat in her bikini, in a hot tub... they all subscribed to her channell, there were nip slips and dirty talk, and one managed to subscribe to her only fans before the parents caught it and stopped it all. This all happened in a matter of 2 to 3 days.
