I think a fascist state would be far less censorious than the international mega-corporations today who decline payment services, ban books from their platforms, kick users off for simply mentioning the names of dissidents, retroactively delete videos that didn't violate terms of service but now do, and even deny dissidents the ability to register domains.

The association of fascism with censorship I think comes from a libertarian standpoint, from which all other forms of government look censorious and authoritarian. But actually, through a strong state, more freedom can be preserved, especially if that state is grounded in the truth, thereby not fearing its revelation. In contrast, a left-libertarian society leads most probably to our current situation with corporations as states-unto-themselves, based on deception (marketing) and therefore fearing the truth, preventing people from seeking it. (See Reddit's decision to shadowban users who post links to saidit.net, or to outright block links to thedonald.win; they are motivated to censor their competition in our left-liberal/libertarianish society).
