What compels advertising and marketing types to rip off the LiveStrong brand?

I just ran across another advertising campaign that’s mimicking the Lance Armstrong “LiveStrong” campaign. It’s “Army Strong.” Just saw it on ESPN. Just like “Fan Strong” for the Los Angeles Angels of Anaheim. I’m sure there are others.

Am I just being crabby or is that weak? (Or is using the word crabby weak?). This tagline/marketing piggybacking reminds me of the “Got Milk?” campaign parroted endlessly for more than a decade. Got Sand? Got Surf? Got Weed? Got Faith? Got River? Got Soccer? Got Brains?… Barf.

Does anyone have an original thought? Or is there some science behind this cowardly mimicking?

Please comment if this annoys you as it does me.
