My kid and his friends use FaceTime instead of calling and will often be on it for hours while gaming. It's much easier than a call for 3+ people. We are in the US but I imagine they use whatsapp or whatever the same way other places.
I work for a smaller org (less than 50 ppl) and we are generally required to have cameras on in meetings.
$2 pizza and $3 ice cream/ smoothies here, YMMV.
