Internet privacy is an oxymoron. I know this take will get me shot on the fediverse, but trust me.
We're using a huge stack of protocols that were never designed for security or safety let alone anonymity and now we're trying to bolt anonymity on top of them.
Even though tor and SSL are engineering marvels, we're trying to build bookshelves out of mashed potatoes.
The state of software is that security can never, ever be assured. It's all so dreadfully bad and engineered.
