IS SUBSTACK THE “LAST, BEST HOPE FOR FREE SPEECH?” I think it’s proved that people will actually pay for journalism when it’s interesting and useful (as opposed to solely click-driven) but Substack is still a single point of failure – and the pressure to censor that will be brought on its management once enough powerful people get angry is immense. It would be wise for them, or someone who’d want to compete with them, to come up with a monetized, distributed model to flee to when the time comes.
