Then I changed my email address back to what I want it to be, and I have ceased caring. I will continue using facebook to coordinate bar meetups with my friends.
I think you kind of hit the nail on the head with your last sentence. You will continue to use the service for fairly meaningless tasks. It seems Facebook wants its users to use their service for more than that. So while this debacle may not make many people delete their accounts, Facebook may find its apparent goal more difficult to achieve going forward.
I've always had a very healthy mistrust of facebook, based on their past actions, and I never let facebook sync up with anything else I use (and I don't use services that only authenticate via facebook). They simply can't be trusted with anything important; not because they are incompetent, but because they have no moral compass that prevents them from screwing users over.
This is just one more reason for me to continue to silo facebook off into its own world, where it knows nothing about the rest of my life, particularly the really important stuff.
No, I won't leave Facebook entirely over this, but I did just uninstall their application on my Android device. I simply don't trust them to have access to my contact list.
Frankly, I didn't trust them much before: I'm sure they were mining it, which is not something I would explicitly consent to. However, now I no longer trust them to not break it, so I've removed their access to it entirely.
I see they actually created a way to remove the FB app from an Android device. Back when they hoovered up phone contacts into their database, I tried to break the connection, but all I could do at the time was delete my entire facebook account. Been pretty happy not wasting my time there, as I see it devolving into pseudonymous games, meme one-upmanship, and picture albums kids will mostly later regret.
If you installed Facebook yourself, you can always remove it. You can't remove it if your carrier or manufacturer put it there (at least not withput rooting). AFAIK Android 4.0 allows you to deactivate these apps, effectively removing them witgout deleting the files.
That assumes you CAN uninstall it. Many devices come with Facebook preinstalled and not removable (because Facebook worked a deal with the device manufacturer or the cell company).
I don't have the entire Facebook userbase added as a friend, but I haven't seen a single post on my newsfeed about this problem. Yet every second day I see posts about how much someone hates Timeline.
It will be are for people to completely leave Facebook. What Facebook needs to worry about though is that people will stop using the service as much. People may be less likely to integrate Facebook apps on their phones.
All of this could lead people to use FB less, which is is exactly the opposite of what they were intending.
I very much doubt that. Statistically no one will leave FBook over this.
