You're conflating a single anecdotal example with the overall issue. Of course this vote doesn't mean that all websites that are free, open, or focused on knowledge will go away. What it _does_ mean that your ISP can now sell the fact that you post here to Microsoft, who will know that malchow is you (tied to your real name, since the ISP knows that), and now Microsoft can start targeting you in new and exciting ways…
By the way, the fact that you cannot predict Microsoft's "new and exciting" ways of targeting me is a great example of why your argument is unconvincing. Do you really want me to believe that, as long as we kept this rule in place, network providers would never conceive of novel ways to participate in the advertising business using the network-level data they enjoy?
Your best friend, if you are looking for a no-tracking digital lifestyle, is the free market's likelihood of delivering to you just that. It may come at a premium price, which I assume you'll be happy to pay. At the moment, you are just making everyone else pay a premium price for the no-tracking digital lifestyle you prefer, and relying on bureaucrats in D.C. to patch up the rules from time to time to keep up with novel targeting methods.
