Since people don't know whether your speculation is wrong or right (unless there's an FB developer around), they can only judge whether your speculation is plausible or not. And I guess they mostly thought it wasn't plausible.
When I wrote "could you explain why you think I'm wrong", I was expecting that people who had reasons to believe I'm wrong would respond, and would explain those reasons, not that someone would explain to me how speculation works.
If you think I'm wrong on a technical level, could you please explain how?
