Well, content blocking happened before (see wikipedia vs net neutrality). So I suggest we let our judicial system know what people wants and wants not (that is, legislate now). But to me, content blocking is not the worst scenario - I agree that content-blocking companies would hear quickly from their customers. No, my real fear is that they could give lower priority (more latency) to web services that are competing with their own web services, or with their partner's web service. What if Bell, somehow close to Microsoft these days, gave lower priority to Google in favor of MSN search engine? You'll feel Google is slower without knowing it's because of your ISP. Well, actually, they (the IPS in general, not Bell specifically) might already be doing something like that without the public knowing. How could we ever find out? How could the public be safe if there's no legal structure to limit what can be done, and how what's being done can be verified? I'm not afraid of legislation. I'm more afraid of companies, for which the only real concern is profit, free to do whatever they please.
