Great question. The company just announced a partnership deal with Miami Dolphins and it is only my assumption that it was the team who pulled out. I may be wrong but my money would not be on Spongetech canceling a deal while they are pretty much stealing the ad space.
The point is that all the sponge wavers point at the ads as proof that everything is hunky dory when in fact the signs were up before the problems, as were thhe TV ads, and they have been paid for so they will get some daylight.
