If the actual choice requires me to install an app then I care quite a lot and will probably decline to join in.

I don't think that I am the only one who feels this way.

Then life moves on without you in the club.

Unless they are chosing something super obscure and sketchy, most club members are going to be fine with the leader just saying, we're picking whatsapp, either join or dont.
