Privacy is a group inoculation. Even if you self-host, there’s nothing to prevent your information from being inadvertently gathered by your friend who hasn’t taken the same steps. Not to mention that self-hosting is really hard! At its simplest, you need to know how to use command line tools (or, if you’re using shared hosting, be comfortable with FTP). At its hardest, you need to have some server administration skills. For those reasons, I don’t think self-hosting is a real solution to the problem in itself. There are lots of other great reasons to self-host: having full control of your web presence and data, if you have the means and the skills, allows you to better represent yourself online. — Escape from Google
