Of course it doesn't? Who cares. I deleted my account too but that doesn't mean much.

I'm highly skeptical this outrage cycle will go on for long enough to seriously impact their userbase. Absent a proper competitor to Twitter. I've been part of enough internet boycotts of them to be cynical about their odds.

Also I'm not sure why you're having trouble finding Facebook data... just google it if you care so much about dismissing their obvious dominance. And WSJ paywall is easily bypassable.
