A reasonable pitch to users. But to advertisers and others? Not so much.
If you create a social platform that appeals very strongly to a small minority but where the content creates strong objection in a larger group, then companies don’t want to be seen there. And running a social media platform is expensive. User demand isn’t what I’d worry about, it’s sales (of ads and paid subscriptions). I don’t think there is a market for either of those if Parler/Gab were any indication.
