Could you give an example of such a "messaging app"? I don't have any "messaging apps"; although I do have a 'phone which supports SMS (I assume it supports email too, although I don't know how comfortable email would be without a physical keyboard).
Do you have examples in mind about how my life might be "a lot more difficult" than if I installed the sorts of software you allude to?
I can't speak to your life, but not having Whatsapp would result in my being left out of some conversations and activities I want to be a part of. Email or SMS could theoretically substitute with reduced functionality in most situations; Matrix could substitute with no loss of functionality. Most of the time the other people in the conversations prioritize their activity/task/goal/socializing over technical or ideological concerns about their communication tools, so getting them to change tools would be an uphill battle.
In short, unless I'm really important to a group, I have to use what they use or get left out. If I'm the most important person in every group I'm in, I'm probably in the wrong groups.
It's not a heck of a claim at all, it's a pretty reasonable one.
I moved from a country that tended to use Facebook messenger and sometimes SMS (though that was fading), to one that primarily uses WhatsApp. While I already had WhatsApp installed from travelling there in the past, I almost never used it outside of travel purposes.
When I moved, everything ended up in WhatsApp. If I met someone and wanted to meet up with them another day, it was WhatsApp. I'd get added to a group because it was someone's birthday, it was WhatsApp. Many apartment buildings have a WhatsApp group to discuss building related things. It was how I told my landlord that something needed fixing. So on, so forth. Lately there are some people I talk to on Telegram, and a couple on Signal, but most of my social (and other things) organisation goes via WhatsApp. I could uninstall it, but then I'd lose a chunk of social contact.
For me, email has become mostly an avenue for notifications from companies or newsletters. The most back-and-forth I've done with it in a long time was when I was buying an apartment, a lot of documentation and organising was done through email.
As for SMS, no one uses that except perhaps one automated reminder about something every few months.
For example, in Spain, people will not communicate in written form with you outside Whatsapp. You can try sending an SMS, they won't answer to not risk being charged.
Your friends will communicate and organize events only on Whatsapp. Your colleagues will have social interactions on Whatsapp, even send you work messages when on the go. Your landlord will communicate via Whatsapp, including sending you utility bills to pay. The person you want to buy second-hand stuff from communicates via Whatsapp. The real estate agent trying to find you a place to live will send proposals by Whatsapp. Many businesses advertise customer support on Whatsapp also, although in that case it's never the only option.
It's not literally impossible to live without it. I know some grandparents without smartphones. But it does make your life a lot more difficult.
I'm not disagreeing with this, especially the social aspects, although I would point out:
> Your colleagues... even send you work messages when on the go.
> Your landlord will communicate via Whatsapp, including sending you utility bills to pay.
> The person you want to buy second-hand stuff from communicates via Whatsapp. The real estate agent trying to find you a place to live will send proposals by Whatsapp.
In each of these examples, the other party has something to gain (a client; a bill payment; offloading some work; etc.), which I'd wager is enough to tolerate the minor inconvenience of sending an SMS/email.
