They do not like the solution proposed (Title II reclassification)
Here's an abbreviated list that they pose at the bottom
> We do not support reclassification of broadband as a telecommunications service under Title II for at least four reasons:
> 1. Title II is unnecessary
> 2. Title II poses significant legal risks
> 3. Title II has proved to be a failure
> 4. reclassification .. will create a huge cloud of uncertainty over the entire broadband industry, thereby retarding investment and innovation.
