Let's start with social media. The entire model to date of social media networks is that we are the product, as the product is free. As the product, social networks mine and sell extensive amounts of data that they capture on each and every one of us.
Therefore.. having privacy on traditional social media is an oxymoron.. but it can be done if you use a platform that doesn't require KYC/AML data, if you use it in conjunction with other privacy tools, such as a VPN, anonymous email, etc.
Twitter bucks the trend somewhat, as it mines and sells data on you, but doesn't require KYC/AML by default. Crucially, this means anon's are not deplatformed... but for how long will this last? Premium users are already compromised.
Elon Musk is a champion of permissioned speech, not free speech. Nevertheless, he is making a concerted effort to support people's right to speak (relatively) freely. As a centralised company, it's perhaps only a matter of time before his gallant efforts are reigned in. After multiple threats from the EU, Brazil is the first to try to actually force his hand, the question is when, not if his hand be forced?
Twitter aside, if you want to use platforms that embrace truly embrace privacy and/or resistance to censorship, you'll have to settle for a platform with a smaller, and hopefully growing reach:
🔻 Nostr is a decentralized social network that focuses on privacy, free speech, and user control over their data. It uses the Noise Protocol for end-to-end encryption and allows users to verify each other's identities. Content published here is more or less immutable, it cannot be removed by he who posts or he who tries to censor. Try the clients: Damus, Primal & Amethyst and hook it up with a lightning wallet to zap Bitcoin tips.
🔻 Mastodon is a decentralized, open-source social network where users can join servers (called "instances") run by different organizations or individuals. This model promotes permissionless access while allowing for more granular control over content moderation and privacy settings.
🔻 Diaspora is another decentralized social networking platform that emphasizes user privacy and data control. It allows users to create their own "pod" (a personal server) or join existing pods, providing a more permissionless alternative to centralized social media platforms.
