This is where we have a glitch. I believe all Internet platforms have a duty of care. We need regulation that is what I would call “best in practice” to protect all children and vulnerable individuals on the Internet. Under the age assurance umbrella, you have numerous tools. If they are legislated to happen at the device level, everyone gets protected.
Picking and choosing just certain media sites is not the only answer here. Very few people are protected when you take that approach. You need a broader approach to all Internet providers and all Internet platforms.
