TL;DR You need a realistic threat model.

Well that's true but ehh still it doesn't happen too often. If you want to keep your data away from the government then it is a danger. If you just want not to give the unethical advertising and data mining companies your data for free so they don't have profit (like I do), you don't need to focus that much. And if you're concerned about your partners and friends getting the data, you have to reconsider their role in your life ngl.

That's why you get a separate identity or device for everything that requires your real name and NEVER EVER tell your real name online (they even teach it in schools nowadays if you didn't know).

If you want a public life with posting everything that happens to you, you can't protect much except the metadata. Other than that there is some data you can't protect but my previous points help with it and, once again, it depends on who you want to protect it from.
