Earlier quoted context omitted.
Agree on the lack of features front. I actually preferred the simpler design FB had back in 2013 or so before the big redesign. After that everything seemed to get busier and louder . Usability took a hit after that IMO.
I've not used Facebook in any personal capacity but the same thing happened to Twitter, especially in the speed department. Twitter is so slow now that I don't use it.
It was very clear cut at the time, Twitter did a 180° and left RSS along with lean HTML and got super slow and noisy (so much for adtech.) Facebook started changing its appearance compulsively and adding random crap. Then it removed itself from search engines for vendor-lock maxima.
