On a recent Monday night, a dozen marketing companies, research firms and other personal data guzzlers got reports from my iPhone. At 11:43 p.m., a company called Amplitude learned my phone number, email and exact location. At 3:58 a.m., another called Appboy got a digital fingerprint of my phone. At 6:25 a.m., a tracker called Demdex received a way to identify my phone and sent back a list of other trackers to pair up with.

IPhone apps I discovered tracking me by passing information to third parties — just while I was asleep — include Microsoft OneDrive, Intuit’s Mint, Nike, Spotify, The Washington Post and IBM’s the Weather Channel. One app, the crime-alert service Citizen, shared personally identifiable information in violation of its published privacy policy.

Yes, trackers are a problem on phones running Google’s Android, too. Google won’t even let Disconnect’s tracker-protection software into its Play Store. (Google’s rules prohibit apps that might interfere with another app displaying ads.)

確かに Facebook は Campbridge Analytica の件以来さまざまな点で批判の矢面に立っているが Facebook に論点を絞るのは問題の矮小化といえる。 もしメディアが意図的に矮小化を行っているのなら，これこそがフィルターバブルの典型例と言えるだろう。

Part of Jackson’s objection to trackers is that many feed the personal data economy, used to target us for marketing and political messaging. Facebook’s fiascos have made us all more aware of how our data can be passed along, stolen and misused — but Cambridge Analytica was just the beginning.
