I guess we're waiting to find out if Trump or someone will start writing there. The current big boys are all non-woke center left/right so they're not actually at all outrageous to the general public.
They are however outrageous to the far-left journos at mainstream publications, which is why there's so much attention focused on Substack right now. Trump won't go anywhere that he doesn't get to own a significant portion of the business, so he'll have to build his own site (which it is already reported that he is doing.)
