I was a bit confused about the spam thing too. Was the intended meaning that URL shorteners indicate the link is spam, or that trading off user experience for analytics makes it spam? (Or in the spirit of spam, or something.) I'd think they meant the second one, except that it doesn't actually make any sense.

I also got a really strong gut feeling of "spam" being used as a "boo!" sign, for some reason.
