Nobody is forcing any device on anybody, least of all the manufacturers. After all, 50% of mobile cellphone users still use basic phones with no smartphone characteristics at all.
While some data downloaded on mobile may be unnecessary, it doesn't have to be that way or be bad. Hence the "mobile first" strategy where you create pages for mobile first. That eliminates much of what would be served to them and the added stuff, like larger images and text, get added on later using server side detection or scripting.
Now, that said, responsive design is a lot more work than a fixed size page but having a second mobile site also increases the workload. One of the biggest disadvantages of that is if the user has to select the mobile site or if its detected server side. But server side detection isn't always reliable.
