I am also not advocating for compelled speech.
Very soon, it will be impossible to buy webscale hosting from anywhere but a half-dozen providers. Should those providers be the sole and exclusive authority of what is or is not allowed on the web?
Airlines aren't permitted the authority to decide who flies and who doesn't. Why is AWS?
This isn't a constitutional issue, or even an American one. It's one about the place that censorship has in our civilization.
A tiny number of infrastructure providers should not have a unilateral ability to veto unpopular speech, especially considering, as we just witnessed, the definition of unpopular can change on a dime with the wind.
Today, it's Parler and Stormfront. What will become the target of censorship in five years? Ten?
Increasingly services are linked to our identities, and bans are lifetime. Will creating new accounts after political wind direction changes endanger one's data storage, email, contact lists, or hosting/publishing ability one day? How many individual people or organizations are really provider-independent and could survive losing all of their data at a host because they once belonged to the wrong faction?
Don't underestimate this risk.
Who needs to stop them?
By which authority?
Who decides what is a lie and what is truth?
Who cross-checks them when they're inevitably wrong?
By which authority?
Simple dismissals like this miss the point. Until there are some good answers to these questions, kneejerk censorship is no solution at all.
Stating falsehoods should absolutely not be grounds for censorship, even the private kind undertaken by hosting providers.
