I'm constantly amazed at the extent companies will go to spy on people so they can better advertise. 10 years ago your tinfoil hat may have been on too tight if you were worried about your devices communicating through sounds above your range of hearing so that your actions could be tracked between those devices, but in late 2015 there was an advertising company doing exactly that (SilverPush and their ultrasound tracking beacons). I've almost completely stopped using non free software, with the exception of drivers and software necessary for games (which I run separately from my main OS), because a lot of it now days tries to shove spyware down your throat at every turn. I will say that, unlike most people, I have been insulated from most of the web based spying as I started globally blocking scripts/cookies and manually allowing only what was necessary for pages to run back in 2009 and used the original Adblock for Firefox before Adblock Plus was released, while I see many people like >>29289
suggest simple ad blockers as if they're something new. I also never got on board with social media.
I wouldn't describe myself as a technophobe however, as I still think it's exciting to see the new technology as it comes out such as the 8k monitors that were announced earlier this year, AMD's new Ryzen processors where I'd be able to build a cute slim mini ITX box that could run all of my games with one of the new APUs coming out if I wanted (I still need to weigh the problems of Windows 10, AMD's PSP, and my games isolated on my network where I can have more external control of what that machine can connect to vs Windows 7 and my games in a VM on my main machine), and SBCs becoming more powerful so that even though netbooks are no longer produced I could still possibly upgrade an old one with some work.
