I disagree. I think it is in the benefit of the platforms themselves (e.g. Twitter) to promote equality, tolerance (to different points of view) and freedom of speech, especially to those they disagree with (e.g. Milo). IME it's the "tolerant liberals" that don't even try to engage in intellectually vigorous debate (they'd rather protest, ban, shout, fire their oponents, or call them "hate-mongering trolls").
