Were all doomed anyway.
If x number of friends have your number and connect to y app then your contact list can and will be guessed without your permission.
I say y app because it is of benefit for all the companies slurping data to do data swaps depending on the datasets. Contacts I would assume would be a beneficial swap to isolate friends of users not using y app.
Even though Facebook is an abomination of slurping shite but at least they don't really hide the fact.
