Signal, for those who donâ€™t speak Elon or Edward, is an end-to-end encrypted messaging app. This means that it uses a protocol that ensures nobody â€“ including Signal â€“ can access the content of the messages. Since the surge of popularity from the endorsements, it currently sits at the top spot on both Appleâ€™s App Store and the Google Play Store. Â
These celebrity endorsements were sparked by Signalâ€™s rival, WhatsApp. The Facebook-owned client has approximately 2 billion monthly active users around the world, while Signal has around 14 million. Itâ€™s hard to really call these apps competitors, since a messaging app is only as strong as its network. But while WhatsAppâ€™s network is under threat, Signalâ€™s continues to grow.
This does not include the contents of usersâ€™ chats because those are, like Signal, end-to-end encrypted. In fact, WhatsApp uses the same protocol that Signal itself uses. Â
The fact such a clarification needed to be made, that users did not understand how their data was protected, is the culmination of Facebookâ€™s generally poor reputation with regards to privacy.
It is strange for a journalist to write this, but what matters is not how things are; itâ€™s how things feel. WhatsApp might not share data to Facebook but it feels like it does, in the same way that your phone is (probably) not actually listening to your conversations, but the mass of information about your location, preferences, chat history, all collected by advertisers, means that the TV programme you were talking about only yesterday is now the first advert you see on the site. Â
These â€œcoincidencesâ€� are actually just surveillance capitalism, a manifestation of our every interest bought and sold so we become better consumers. It makes people uncomfortable, even if they might not necessarily be able to put into words why that is.
In the wake of Donald Trumpâ€™s recent attacks on democracy, many users are unlikely to want to hand more power to the organisation that, at least partially, helped get him elected.
And finally, no-one likes to be forced to use something. Facebookâ€™s various apps take up numerous precious slots on the phoneâ€™s home screen, and in the midst of antitrust suits claiming that the company crushes or purchases the competition, the idea that this can be fought against seems to be slowly seeping through to the everyday user.
Does using Signal solve every problem? No. Many people will still use Facebook, or Instagram, or WhatsApp â€“ at least, until iMessage comes to Android â€“ but Facebookâ€™s power is in its user base.Â
Itâ€™s hard to swap from WhatsApp because everyone is on WhatsApp, just as it’s hard to move house when youâ€™ve grown into the neighbourhood, or make friends if youâ€™ve changed schools. But while difficult, and awkward, it is possible. Â
Despite the apparent divine right of these tech platforms, they do not last forever â€“ just look at the vacuum left from MySpace, or AOL, or BBM. Switching messaging apps might not feel like a lot, but it is an acknowledgement of an attempt at a different world built on different principles. That, at least, is a start.
