I have never used WhatsApp, and never will. Despite this, I still feel the need to write an article about WhatsApp since it's the perfect case study to help understand a class of businesses models I call "user domestication". The domestication of users is high on my list of problems plaguing the human race, and is worth a detailed explanation.
WhatsApp wasn't the first instant messenger of its kind, and probably won't be the last. I simply chose to focus on WhatsApp since its recent privacy issues have made it a hot topic.
With the meta-explanation out of the way, let us begin.
WhatsApp's rise {#whatsapps-rise}
--------------------
For those unfamiliar, WhatsApp is a tool that makes it convenient and easy to help Facebook further its core mission: the optimization and auctioning of human behavior (colloquially known as "targeted advertising"). It originally persuaded people to consent to this by allowing them to send text to each other over the Internet, something that was [already possible](https://en.wikipedia.org/wiki/Comparison_of_instant_messaging_protocols), and combining an easy-to-learn UI with successful marketing. It then expanded to include features such as free voice and video calls. Free calls helped it grow to become the de-facto communication platform in many regions. I'm stunned at its ubiquity every time I visit my extended family in India; I'm frequently greeted by looks of confusion when I remind them that I don't use WhatsApp.
Having its own proprietary chat system incompatible with other clients allowed WhatsApp to build a [network effect](https://en.wikipedia.org/wiki/Network_effect): WhatsApp's existing users were held captive by the fact that leaving WhatsApp meant losing the ability to communicate with WhatsApp users. People switching from WhatsApp must convince all their friends to switch, too; this includes less technically inclined friends who had a hard time learning WhatsApp in the first place.
In a WhatsApp world, people who want to keep in touch must abide by the following rules:
- Everyone can only use the proprietary WhatsApp client to send messages; developing alternative clients isn't supported.
- Everyone's mobile device must run an operating system supported by said client. Since WhatsApp developers will only write a client for popular operating systems, the Android and iOS duopoly strengthens.
- Users fully depend on WhatsApp developers. If WhatsApp developers decide to include user-hostile features in the app, users must go with it. They can't switch to a different server or client without switching away from WhatsApp and losing the ability to communicate with all their WhatsApp contacts.
User domestication
------------------
WhatsApp rose by trapping previously-free beings in their corral and changing their habits to create dependence on masters. Over time, this made it difficult or impossible to return to their previous lifestyle. That process should sound familiar: it's eerily similar to the domestication of animals.
I call this type of vendor lock-in
