Last week, Facebook announced that it would allow voters in the United States to opt out of seeing social issue, electoral or political ads from candidates in their Facebook and Instagram feeds.
Whilst Facebook’s attempt to increase the agency of users during the election period is commendable, the binary choice left to voters to either see political ads or not see them at all is a limited and short-sighted one.
Real transparency concerns are still unaddressed

Immediately following the UK general election in December 2019, we worked with Open Rights Group to commission a YouGov poll about public understanding and public opinion about the use of data-driven campaigning in elections.
The poll used a representative sample of 1,664 adults across the UK population.
'Data-driven political campaigning' is about using specific data about you to target specific messages at you. So, for this might involve knowing that you are, for example, likely to…

Other devices on which you might be logged in
You might have used Telegram on another phone or a computer. A good practice after doing so is to logout to make sure nobody can use your account without your permission. If you ever forget, Telegram allows you to terminate any session that is not on the current device you are using. We recommend checking this on a regular basis and removing everything you don't recognise. If you only use one device (such as your phone), this list should be empty…

Phone
The first time you use Telegram it will ask for permissions to use your phone. This is used for the verification process but shouldn't be used later on. However, if you don't change this permission, Telegram is theoretically able to make phone calls on your behalf. We recommend you check the app's permissions to disable anything you don't use within the app, such as permission to access phone calls or location. You will likely find this in your phone settings rather than the app.

In an article for Agence France-Presse, he said, "In my life, there is so much surveillance and monitoring -- my phone, my computer ... Our office has been searched, I have been searched, every day I am being followed, there are surveillance cameras in front of my house.”

Lila’s GoogBit watch vibrates. “You got 6 hours and 57 minutes of sleep last night, including 2 hours and 12 minutes of deep sleep”, the watch reads. “In total, you tossed and turned for 15 minutes only”.

Google wants to know everything about you.
It already holds a massive trove of data about you, but by announcing its plans to acquire the health and fitness tracker company Fitbit, it now clearly wants to get its hands on your health too. We don’t think any company should be allowed to accumulate this much intimate information about you. This is why we’re trying to stop its merger with Fitbit.
Google and Fitbit need the European Commission’s approval before they can merge. The merger would…

The closure of services and some GP registrations, a lack of access to technology, distrust and fear of authorities, unsuitable or insecure accommodation, and reduced income are among the many challenges facing people in vulnerable circumstances in England.

There are few places in the world where an individual is as vulnerable as at the border of a foreign country.
As migration continues to be high on the social and political agenda, Western countries are increasingly adopting an approach that criminalises people at the border.
