The part I find the most enlightening (ie: disturbing) is that Canonical's only regret is that the sales rep used "a poor choice of word" and they will train their salespeople better.
I assume the "poor choice of word" was when the salesman said, "I saw that you spun up an Ubuntu instance". Was Canonical's biggest regret that the salesmen INFORMED the user that they are monitoring installs and linking them to contact information?
Canonical never said "oh the salesperson wasn't supposed to market to you with this information", instead they basically said, the salesman wasn't supposed to TELL YOU that we are monitoring what you install and linking it to personal contact details.
