Substack handles paid subscriptions, which is distinctly non-trivial to "host your own". They've also publicly advertised a strong anti-censorship position, and a lot of their userbase will abandon them if they change stances.

While it's certainly a possible concern, not all platforms descend in to censorship. I think it's reasonable to wait until there's at least warning signs before criticizing a specific site.

From Substack terms (https://substack.com/tos):

> We reserve the right to remove any content from Substack at any time, for any reason (including, but not limited to, if someone alleges you contributed that content in violation of these Terms), in our sole discretion, and without notice.

A lot of platforms unfortunately have these blanket disclaimers. Fortunately Substack hasn't gone down that road yet, while Twitter, Facebook and Google are already over the horizon.

They're not big enough yet, but they're getting there. And they have anticipated that they might need it, hence the language in their TOS.
