I am sorry to see this thread has become quite unpleasant and resulted in the Zoom members feeling they have to come on here to state their point of view.
I have been a regular visitor to the Edinburgh meet ups, since I joined in 2016, even staying overnight in Edinburgh with DH for a few of them. I think the Zoom group, of which I am not a member, could be seen as sub group of people who see each other as friends and are in contact regularly, they obviously cannot invite everyone of us to join their smaller group.
To respond to Kitty's comment about not all Edinburgh grans being included, the Zoom group (I can only hazard a guess as to who is a member,) have additional smaller meet ups, which are not easy for some of us to attend, this has obviously allowed them to become closer to each other, interact more often and develop friendships.
I'm sure they have been a great support to each other, which is to be commended. It's been a very difficult and lonely year for some of us.
In my opinion, it would be best to just let this thread fade away quietly, before it becomes even more acrimonious.
