We are considering an option that blurs out the page instead. Also - we'll add more context to the page.
Our impression (and experience) is that people get more excited about doing something symbolic.
Again, any direct recommendations about how to improve this, and we'll improve it :)
Visibility is the issue, not understanding the problem. I think the message of "the internet could be slower without net neutrality" is the one that needs to be delivered. People generally know what "slower" means.
As I mentioned, a standardized message would probably be more effective, but it's also not something that would be particularly exciting to share on, say, Hacker News.
