I checked it out and I'm pretty sure a big issue will be that it's going to attract an audience and subsequent content that national brands aren't going to consider brand safe. So if they find a model, I can't imagine it's going to be advertising unless it's My Pillow guy and gold sellers. That probably isn't going to float the development of the platform.
I do think there's something to be said for censorship (regardless of whether it's a private platform) and the control of misinformation as well. My point is that I don't think it's sustainable unless they find a subscription model. But given the zeal of the (far) right, it doesn't seem outlandish.
