Summary: Ref T10747. When we import a ".ics" file, represent any attendees as simple external references. For consistency with other areas of the product, I've avoided disclosing email addresses. We'll try to get a real name if we can. (We store addresses and could expose or use them later, or do some kind of masking junk like "epr...ley@g...l.com" which is utterly impossible to figure out.)
