The Short Answer

Because when information is transmitted over the network, extra bits are added to tell routers where each packet needs to go, and to add coding that will help minimize transmission errors. So it isn't quite right to take the number of bits/second and divide by 8 to get the number of received bytes/second. Also, Marketing. You get bigger numbers when you talk about bits instead of bytes, so it sounds more impressive. **TL;DR** – Overhead.
