Of course, this couldn't be further from the truth, but that doesn't matter. The only thing that matters is the public's perception. It's frustrating, but it's true.
So what's the other way to promote DPM? By focusing on the increased choice ("consumer choice" is the most favorable way to phrase it) that will result from instituting DPM or, even better, never even enacting regulations in the first place. Tim Lee has done a great job of doing this in this op-ed, which argues against enacting legislation that would attempt to preserve "net neutrality."
Tim's op-ed sounds very positive to me. Even though he's arguing against the populist position (which says that we need net neutrality to maintain equal access to the internet), his argument comes off to me as slightly populist (i.e. it has popular appeal).
To sum up:
- more profits = bad public perception
- more consumer choice = good public perception
