Click the button on the top-right it should show a clock if you want to order by date. The first relevant result then is Octodroid, albeit there are lots of irrelevant results. OctoDroid was last updated 2 months ago.
But I’m not here to defend the UI. 
I’m just saying the information, including the last-updated date, is presented to you. And there are REAL CONCRETE benefits to your privacy to use F-Droid. I provided not 1, but 3 real world cases that directly impacted me. I’m not a maintainer. I don’t publish packages on F-Droid. I’m just a user. And this guide seems both wrong in spirit, and factually wrong in the words too “less strict” in the context of privacy, means the apps are more likely to reveal your information.
Of course, probably 99% of the apps people download from the Play Store have trackers. I don’t think anyone in this conversation can show you one application with a tracker library and no notification on F-Droid now. And, many of the applications without trackers are ONLY available on F-droid (and not on GitHub).
