I did the same and I'm not really regretting it. It's somehow sad, that I'm now missing the conversations and plannings of my family and somebody always has to send me something on another way, but I'm okay with it.

I'm feeling much better, since my phone stopped distracting me all the time and I lost the permanent need to look at my phone. Of course I'm using Telegram as an alternative, but the app is not running in the background and I have to open it myself if I want to check messages.

So in the end, I've exchanged communication to productivity and I don't regret it.

I don't like the open end of the article. It does not point out, if the author thinks to use WhatsApp again. It just talks about how we sell our data to use a service.
