In this particular case, Subway’s P.R. gaffe last year was not repeated this year. Last year, the sponsors specifically excluded homeschoolers in their writing contest and caused quite an uproar. “No home schools will be accepted” came off as a bit harsh and unfriendly.
There was such a rumble that a google search for “Subway contests” still calls up a front and center look at the 2008 threatened boycott.
This year’s contest has no mention of homeschoolers. Sometimes marketers realize that less is better.
