Although I also know a handful of (euro) people who do not have Whatsapp, and a lot of the "missing out" can indeed be absorbed as you described. However, lots of people have a need for Whatsapp which cannot simply be ignored by walking on the beach. It is all about social trade-offs, personally I have almost all apps installed, most of them (or at least the group chats) muted. Some friends are signal only, some prefer telegram etc... sometimes it is just more "social" for you to adapt to a group. If the situation is that others want something from you, you can dictate the forms of communication, however it is quite legit for people to want to be a part of a larger group. No need for snarkiness.
