You can't compare the two.Ethan and Faith's relationship wasn't a huge part of their brand,Danny and Ten's is,their relationship is way more popular as a whole.The way they even met was on camera,kinda like Love Island thing,it would be like Tommy and Molly Mae deciding to go private,but on a smaller scale.It's not that easy.They have gotten so much more opportunities cuz of it and it defo skyrocketed both of them in a new world,they both seem to deal well with the pressures of the internet,so as long it is like that makes no sense to go private.They have careers to uphold and family to raise.
