Why are purchased muffins are not true muffins?

Purchased muffins often differ from traditional homemade muffins in texture and flavor. They tend to be larger, denser, and sweeter, resembling cupcakes more than the light, fluffy quality of true muffins. Additionally, many commercial muffins contain artificial ingredients and preservatives that compromise their freshness and taste. This results in a product that, while convenient, lacks the authentic characteristics of a homemade muffin.
