If you use an RSS aggregator like Feedly, Newsblur, The Old Reader, or Inoreader, it's safe to assume and expect they will track you. It's shitty and there is (was?) no real alternative.
What then? Do I have to maintain my own RSS aggregator server so I can read my feeds on multiple devices? Or do I have to restrict myself to a single device?
I don't know what world you're living in, but none of the "consumer facing" software I use has built-in tracking, including my RSS reader.
It's actually sad that apparently even the tech literate people on HN have given up and just accept that creepy corporate tracking is a way of life.
What's even more sad is that I know many people here work for companies that do this and they go along with it.
