It's nonsensical rage/click baiting garbage. You are the product, not the user.

Anybody who hasn't used FB in a long time almost certainly has 100s if not 1000s of posts from friends and family that they missed. Instead of this garbage it should be "Hey, we haven't seen you in awhile! Here's all the fun and important stuff you missed out on."

That might actually get me to engage with the platform because that would be putting my needs first and foremost. But that's not what FB does and not what FB ever did. Zuck never had our best interests in mind, so why would it put our interests first?
