What? How is that 'the whole point' of an RSS reader?
Instead I use Newsbeuter[1], a great standalone RSS client. It runs completely on my own machine. I don't have to give out my email address to anyone else nor do I have to tell the owners of any service what I read or what my interests are. That's completely my own business.

To be able to subscribe to information sources without having to give away any personal data, start getting spammed, etc. Seems especially relevant in light of all the recent (if belated) privacy concerns surrounding social media.
Services you should handle yourself on your own computer (like RSS feed reading) can be done for you but when they're done for you they become "Service as a Software Substitute" or "SaaSS" (see https://www.gnu.org/philosophy/who-does-that-server-really-s... for more on that).
A SaaSS RSS feed reader grants others power over what you're allowed to read, when you're allowed to read it, and that choice also empowers others to track you in your reading. If you don't value your privacy you'll lose it and then you'll likely come to regret losing it after it's too late and you've given trackers enough information to predict your habits.
