I would also like to know how is WhatsApp exploited to keep my attention, you think I randomly search for users or not even sure how could I keep attention to it without actually writing or reading messages.

There are alternatives. Signal is already known even by non-techies. Matrix is not perfect, but usable and it can be setup in a way to bridge with other protocols, like Discord, Telegram, XMPP and even whatsapp.
And what device and operating system not from Big Tech you use to run these "alternatives"?
You are still being tracked, your data is still being available to every site you visit and has tracking codes from Facebook and your data can still end up on some shady exchange.

I am running /e/OS, an Android base without Google bits, on a Fairphone 3. It has its own app store that proxies to Google's, so you can use any app that works with microg. You can also use F-Droid, which gives you a huge catalog of FOSS alternatives.
