Let's not pretend someone who sends an AI note taker, which also implies they have time to read notes taken by an AI of a meeting they couldn't find time to turn up for is someone lacking in time.

The prerequisite of reading notes written by an AI means you have time.

They should just be honest and say "I don't need to be in this" or "I don't want to be in this" rather than pretending they do.

This doesn't follow. Plenty of hour long meetings could easily be summarized in a paragraph. Having the time to read a paragraph does not equate to having time to sit through an hour long meeting.
