Entire countries have ceded their b2b and b2c communications channels to WhatsApp.

End users don't give any thoughts to privacy, generally speaking. Either they've "nothing to hide", or they have given up due to an overwhelming sense of helplessness and loss of agency on the matter.

It's not even a decision anymore. They just type their phone number (aka permanent tracking unique identifier) into the new app and smash "agree".

My customers are on Whatsapp, my suppliers are on WhatsApp. I can fight WhatsApp all I like but that won’t change, but they will change where they spend their money and whether I can give them my money.

At least when you create a completely new group, you could try to change things.

I don't think the invite-only nature of the group is due to privacy but rather moderation. It seems the point of this group is to assuage shame

> Moore ended up creating a private and invite-only support group on Facebook

I read GP's comment as being more about the 'on Facebook' part, not so much about 'invite-only'.
