Oh yes, I wasn't trying to imply that any party was at fault here - just that the outcome is unfortunate.

This isn't just limited to communications tools. For example, people might have dietary restrictions for non-health reasons (religion, environmental impact, etc) that others do not share or even understand. I don't mind accommodating those (to a limit) e.g. when picking a place to eat, but it is a burden placed on people around them. That's just the way it is, I guess, and I suppose all people can do is try to minimise the burden, and to be accepting of those placed upon you.
