I think I have figured out the method to Meta's Madness
I think that a hint to what Meta is up to became clear just a day or two ago. They made an announcement that shot their stock shares up 10%. Meta is going to be renting out their excess cloud servicing capacity, just as many of the big tech firms have been doing. I think they are purging Facebook and Instagram of inactive, bloated, not profitable accounts, so they can use that space to sell/lease/rent. It is a very lucrative business model, and why give you the space for free if they can sell it?
This is, I believe, the most logical explanation. Yes, the Ai bot may be misinterpreting the multiple excuses Meta probably gave it to clear out accounts, such that they are being tagged incorrectly, like with CSE designation, but the results are the same, the accounts are being purged. It may explain why they only archive your materials for a very short time... Time is money, and Zuckerberg knows that formula well.
