Anyways, I maintain an 'Ads & Tracking' blocklist that I believe is pretty reliable and you are welcome to give it a try if you like: https://www.github.developerdan.com/hosts/
I've been maintaining my list publicly for over a year, and I've got to say its not always clear what deserves to be blocked, what should be blocked but can't be due to broken functionality, and what is legitimate like the OCSP servers. Everyone has their own personal level of expected privacy vs functionality. Its impossible to make everyone happy. I just wanted to say that being a maintainer of these lists isn't always easy. The obvious example you provided with (ocsp.apple.com) isn't exactly obvious because it _could_ be used for tracking, and it certainly isn't need for functional reasons (although I would argue that it is needed for security reasons). Anyways, there is a lot of gray when it comes to blocking and you can't make everyone happy.
