Facebook does make changes from time to time which makes it a bit of a cat and mouse game to keep these things working and that can easily get tiresome for people. Also some people might find the initial time investment to create these things to be too much.
There is another post in this thread where someone mentioned that for many people (but apparently not all???) including myself, browsing to https://www.facebook.com/?sk=h_chr tends to show your friends' posts in chronological order like many of us prefer. There are also several people who mention that using ad blockers like uBlock Origin do seem to be fairly effective at blocking most ads and other unwanted suggestions in Facebook and it does seem to work for me.
A good portion of people here on HN would be capable of writing it.
That nobody does shows that there is not really a strong preference for this type of experience over the current suggested/ads/friends mix.
