When the largest accompanying FB news headline is: "Over 400 million Facebook users' phone numbers exposed" this feels like the most poorly timed product launch.
I (physically) don't live in SV or its bubble, and I can assure you, the news that Facebook isn't necessarily trustworthy is getting out there to "the masses". It isn't necessarily changing people habits yet, but the process is certainly started. By the time it causes noticeable problems for Facebook, it may be too far progressed for them to do anything about it.
Turns out, they can't deliver on this pretty universal feature (even Twitter has it), so huh yeah, let's talk about how great they are again.
