It started when they introduced the non chronological timeline. Everything from then on was about driving users to use the app more as opposed to being a tool to connect friends.

Thanks to facebook I have met many friends throughout the world, including my now wife, and have managed to keep in touch with them as I travel the world and land in my friends home countries.

It is so sad that the tool I'm describing doesn't really exist anymore.

And the non-chrono timeline was said to be necessary because friends are posting too much to keep up with.
