Apparently WhatsApp is so integrated into several countries' cultures, you cannot live without it. Like literally - some examples I remember are food deliveries (during lockdowns) are only available through WhatsApp, as are scheduling hospital visits, anything involving schooling, I think I remember lawyers sharing documents, and so on.
I got my first smartphone in 2019 because I watched the world around me gradually change to the point where an Apple or Android phone was expected and became inconvenient not to have.
Modern life absolutely depends on being able to connect to the Internet in some way. For a lot of people, that's a smartphone, which is cheaper and more mobile than a computer.
Like, my life is proceeding just fine without either WhatsApp or Oculus products. Or a Facebook account that I use, for that matter.
(edit: For the record, the reason I am not happy with the precedent is that isolating communities like this seems to usually just serve to increase radicalism rather than remove it.)
