Perhaps Facebook are partly encouraging the clickbait weirdness to give the continued impression to those that are still using it, that there is something to use.
Over the last 4 years I found Facebook an entirely useless vehicle for customer engagement, instagram was marginally better but after the change that got rid of the time based sorting, it became useless as well.
It wouldn't surprise me if Facebook has become a ghost town, inhabited only by those who have become addicted to the posts that feign engagement i.e. somebody is asking ME a question! I am important, I want to be heard. It might just be a complicated scheme to keep the share price high. It doesn't necessarily have to be something nefarious.
At some point I stopped commenting or Liking any post which already has more than ~10 Likes or comments. In some sense it feels really strange to me that people bother to engage with content where their engagement is essentially invisible within the crowd.
It works. I can't even remember what normal Facebook looks like. I've lived like this for the last 5 years.
