Why did NG DEGRADE their product

Was one of my favorite apps. However, the "upgrade" greatly diminished the product. Why would NG do that? Pressured by some other company to give a view of the terrain from 50,000 feet, and not the earlier version which have much close up views of roads etc. I paid $1.99 for the upgraded version only to learn that the map level was useless!!!!
