I decided to take an old 32-bit dust bucket of a PC I had laying around and turn it into a DNS filter using Pi Hole. It immediately started blocking 30% of the traffic going out of my computer which is almost exclusively Microsoft phoning home about who-the-fuck-knows and Google logging what I had for breakfast. Where the hell is @KoalaRimjob to give me the Microsoft Certified Professional™ spin on this. I got paranoid and added about 200 spam lists to the database but then it started blocking facebook and twitter altogether (not necessarily a bad thing). It's pretty eye opening to see the amount and frequency these operating systems send back user data. I haven't connected my phone to the pihole yet but I'm expecting similar results with my carrier needing to know my GPS coords every 60 seconds.
