Welcome to the era of bad OPSEC and no privacy, Max.
I'm also fighting this by using Free Software and GNU/Linux.

It's hard to be private online. I made this identity to be exactly that. There are steps a person can take though. Linux Mint is quite a good Operating System for a daily driver especially for someone who doesn't want to constantly tinker. Some would argue that Mac is actually more secure, but something about Linux feels right to me.
Mac is weaponized proprietary BSD really, all things considered. Like Windows, Mac has backdoors that devastate OPSEC.
I'm a FOSS user too, so I know what that's about to some extent.
