You may have missed the point that in Europe, many many things are organised via WhatsApp. Kids football clubs, dance clubs, parents' evenings, school closures, social club outings, ...lots of things.
Other people are saying that in their countries, Health Services and bank transactions are coordinated via WhatsApp.
It's not just about messaging your friends, and for many people, "opting out" of WhatsApp is not a viable path.

I live in the UK. I understand that people arrange items via WhatsApp but it seems baffling to me. Why not just use email to notify people??
When you sign up to any service, they ask for an email address. They don't ask for a mobile number necessarily, and there is never a "my mobile number is on WhatsApp" checkbox. Why is the assumption of the organiser that you're on WhatsApp your concern? They have assumed you're on a certain platform, and it's their mistake.
It reminds me of the tidal wave of people suddenly abandoning their own websites and instead using "Find Us On Facebook". They might as well put "Use this keyword on AOL".
Facebook is not the internet, and WhatsApp is not the only communication method.
Perhaps it's baffling, and perhaps I agree, but one cannot deny the reality. They don't use email, they do use WhatsApp, and not using WhatsApp is effectively impossible for people in that situation.
Then the reality is insanity!
My mind is blown.
You can be as upset about the state of things as you want to be -- yes, it's wrong and broken and unfair -- but you can't change the state of things by just wishing hard enough. The GP's point stands, things are organized via WA, even though they shouldn't be, so your choices are exactly these:
I am not upset about it at all - I think you are projecting that. I don't use it and it doesn't affect me. I was just presenting the alternative mechanism of using the established communication method of email for notification of events since an email account is requested for most things (tax returns, bank account, most accounts).
