WhatsApp vs Telegram vs Signal. The balance between practicality and privacy.
WhatsApp, the world’s most popular messaging app, updated its terms of use and privacy policy a few days ago. In a pop-up notification it asked users to accept new terms in order to keep using the app beyond February 8, 2021. Taken unaware, users have begun trickling to more privacy-centric messaging apps like Signal and Telegram, also in the wake of data-sharing practices with its parent company – Facebook, and the very mediatised Cambridge Analytical data scandal.
Of particular concern to users is the removal of a passage in the privacy policy that had allowed users to opt out of sharing WhatsApp account information, such as their phone number or location, with Facebook.
Interestingly, WhatsApp has been sharing information on the majority of its users with Facebook since August 2016, when it rolled out a major update to its privacy policy. Only users that opted out of sharing data with Facebook at that time were exempt from the policy, and will continue to be. In other words, those not on Facebook will not be subjected to data share, in context.
Privacy International tweeted that the “accept our data grab or get out” approach is “pretty far from what consent should look like under laws like GDPR”.
Several high-profile social-media users have announced they were deleting WhatsApp, and began guiding users to alternative messaging apps Signal and Telegram.
The most notable push came from Tesla CEO – Elon Musk, whose account is in the top 50 most-followed Twitter handles with circa 42 million followers. His tweet, “Use Signal”, was retweeted by Twitter CEO Jack Dorsey.
Signal and Telegram have subsequently witnessed a spike in downloads. More than 100,000 users installed Signal across Apple and Google app stores last week, while Telegram was downloaded nearly 2.2 million times. Meanwhile, WhatsApp installs fell by 11% in the first seven days of 2021 compared to the prior week, reaching 10.5 million downloads globally.
Signal dethroned WhatsApp as the top free app download in India, Germany, France, Austria, Finland, Hong Kong, and Switzerland, as on Saturday, January 9, 2021.
On Jan 15, the WhatsApp blog stated delaying the data share until 15th May, perhaps in an effort to mitigate the user shift, but the jury’s out on whether this would mean a rethink towards a personal data protection or just an adjustment of the bureau.
The Signal texting platform is open-sourced which means it’s completely transparent — anyone in the world can look at the way the texting app functions (its code) and make sure that there is no misuse of user data in the background.
The company is financed through a series of grants and donations that are offered either by its users or privacy advocates across the globe, eliminating the need for any kind of data collection or tracking for targeting ads.
In an effort for full disclosure, Elon Musk announced he is also one of the donors to Signal, and intends to donate again in future.

The right doers vs the money bags
Signal was actually created by one of the founders of WhatsApp – Brian Acton.
Acton was a part of WhatsApp when it was acquired by Facebook in the year 2014, for $19 billion. However, he decided to call it quits at the social media company after CEO Mark Zuckerberg and COO Sheryl Sandberg were coercing Acton to monetise the texting app, which was something he remains strongly against. His exit in 2017 from the company cost him approximately $850 million in stock that he left behind.
Chris Hughes is another advocate of privacy, and it is a poetic paradox that as founder member of Facebook, Chris used to huddle with Mark Zuckerberg in a Harvard dorm room, building Facebook from scratch, and today, he’s huddling with regulators to explain why Facebook needs to be broken up.
SWIFT vs Ripple
Collating the above to the world of Financial Services, the case of SWIFT vs Ripple comes to our mind, with SWIFT as the Goliath now facing a challenge by Ripple as David. In this instance, as outlined in our previously published article in May 2019, the issue remains one of disruption and privacy on the one hand, with reach and practical application of a user application on the other. Ripple continues to make headway again SWIFT which ironically was a system conceived and commissioned (unintended pun) by banks!
