Apple, Google, Amazon, Twitter, Facebook, Reddit, Discord, and Snapchat have banned Trump and his closest allies. They have a right to do this.
Nevertheless, such a purge has never happened before, and this should be alarming. These companies could at any point go beyond banning myth-spreaders and start censoring everyone who disagrees with certain positions.
I protect myself against similar bans by self-hosting as much as possible, not relying on the cloud, and preferring technologies to services.
Being immune to cancel culture is more important than ever.
