It appears the company is located in NY. If the muffins have no preservatives, freezing them will act as a preservative, extending "shelf life" and also increasing the geographical area in which they can be sold. You can defrost them in the microwave or just sitting on the counter. Once defrosted... idk what their "life" would be... it seems best to just defrost one and then eat it, rather than defrost a bunch of them and eat them over several days' time.
The danger of defrosting stuff on the counter has more to do with protein foods such as chicken, beef, pork, fish (rather than baked goods). You don't want to do that. They should be defrosted in the fridge or in a large bowl/the sink filled with cold water. Change the water, make sure it stays cold. When the meat is defrosted, refrigerate it til you're ready to cook it. I usually put it in the fridge when it's mostly defrosted, to let it finish defrosting there, just to be on the safe side.
