Privacy

Safari on macOS offers a means of deleting saved site-specific data (cache, cookies, etc.) under Settings > Private > Manage Website Data.... Your options from there include searching for and deleting specfic content vs. vapourising everything. The latter option is the safest from a privacy and security perspective; but if you’re interested in focusing on specific cookies and other privacy leaks, you have to search one-by-one. The following script can be used to manage automate this.

Background

The surveillance capitalist economy is built on the relentless tracking of users. Imagine going about town running errands but everywhere you go, someone is quietly following you. When you pop into the grocery, they examine your receipt. They look into the bags to see what you bought. Then they hop in the car with you and keep careful records of where you go, how fast you drive, whom you talk with on the phone. This is surveillance capitalism - the relentless “digital exhaust” left by our actions online.

While largely opaque to most users, Facebook and Google massage any links that you acquire on their sites to include data used to track you around the web. This script attempts to strip these surveillance parameters from the URL’s. It is by no means all-inclusive. Imaginably, there are links that I haven’t yet encountered and that need to be considered in a future version. So consider this a proof-of-concept.

The problem

For example, I performed a Google search¹ for “Smarties”. Inspecting the first link - to Wikipedia, I see:

(N.B. The next installment in my obsessional interest in thwarting surveillance capitalism. Read Shoshana Zuboff’s seminal work on the subject and you’ll see.)

Justification

Last week I outlined my evolving comprehensive approach to thwarting surveillance capitalism - that is the extraction, repurposing and selling of online behavioural surplus for the purposes of altering future behaviour.

This is a simple iOS shortcut to the embedded Safari setting for clearing Safari history and website data. It turns out that when iOS Safari is presented with a URL in a certain format, it will execute preference settings on the device. After a little trial and error, I noted that the setting Settings → Safari → Clear History and Website Data has its own URL: prefs:root=SAFARI&path=prefs:root=SAFARI&path=CLEAR_HISTORY_AND_DATA. By loading that URL through an iOS Shortcut, you can quickly sanitize iOS Safari.

(N.B. I am not a security expert. I’ve implemented a handful of reasonable measures to prevent cross-site tracking and limit data collection about my preferences and actions online.)

Surveillance capitalism is a real and destructive force in contemporary economics, politics and culture. Whatever utopian visions that Silicon Valley may have had about the transformative power of ubiquitous network technologies have been overwhelmed by the pernicious and opaque forces that profit from amplifying divisions between people. While I can’t change the system, I can change my own practices and reduce the degree to which surveillance capitalists, state actors and others who have no rights to my data.

A couple years ago I wrote about a method for deleting cookies from Safari on macOS by employing AppleScript. Now I have a new script that works on OS X 10.14 Mojave. There are ways of surgically removing cookies, but honestly most sites leave so many cookies on my machine that I have no idea what any of them do and to what extent they use them to track me.

Safari

Here’s the script for Safari. Install it in ~/Library/Scripts/Applications/Safari (or really, wherever you like.) When launched from the scripts menu in the menu bar, it will close all current tabs and delete every cookie that Safari has saved. Since it employs UI scripting, you’ll need to give it accessibility permissions when asked.

YouTube comments are some of the most offensive on the web. Even serious videos attract trolls bent on inscribing their offensiveness and cruelness on the web.

Here’s one method of dealing with YouTube comments. Treat the comments block as an advertisement and block it.^[There are other ways of avoiding YouTube comments. I’ve used ViewPure but it’s hard to find content that way even though they seem to be working on making it more seamless to get from YouTube to ViewPure.]

In the showdown between Apple and the FBI over an iPhone belonging to one of the San Bernardino attackers, some would argue that the company should acquiesce to the government’s request that it create a “backdoor” into the device allowing it to bypass the built-in strong encryption. Here’s what people who make this argument are missing: the law doesn’t work that way.

The government filed a motion in the U.S. District Court asking the court to direct assist law enforcement in bypassing the security features of the device. Magistrate Judge Sheri Pym approved the government’s request and ordered Apple to comply. The FBI and others argue that this is a one-off instance of bypassing security. But it is not.
