What a title! If you’re looking for privacy on a public internet platform where you post things for everyone to see, I don’t know what to tell you.
Not sure the author of this piece really understands the concept of privacy.
If I choose to post something to any service - a Lemmy instance, Twitter, a Mastodon instance, FB, reddit - whatever. I’m making the choice to share that info.
A privacy invasion is when that service uses the personal data I’ve supplied in creating a profile/account and the meta data I created along with it and bundles it all up to create a shadow profile of me which they then use to serve me ads or sell to 3rd parties etc. That’s why using Meta products or reddit or twitter or just about any commercially owned service is a privacy invading nightmare and why the fediverse isn’t.
This is a service for publishing your thoughts, your links, etc.; of course it’s not private. If you put something out in the public view, anyone can copy it. That’s not a fact about the Fediverse; it’s a fact about what it means to publish something.
The same is true if you print your thoughts on paper and distribute them as flyers in your local town square. Anyone can grab one and keep it; later on, they can tell people what it says. That is not a privacy failure; it’s a publicity success.
