No. I think Mr. Bernier characterized win-back restrictions as denying consumers access to rivalrous behaviour. It is no doubt what he learned from the incumbent telephone companies, but they're misleading. They make you focus on the small part of the market that has already taken advantage of rivalrous behaviour by moving to the competitor.
In contrast, win-back allows the monopolies to maximize the revenues they extract from the vast majority of consumers. Instead of advertising their best prices and making them available to most consumers, they can keep them quiet and then roll them out in a very targeted and anti-competitive way at the people who choose to lose them. It's far less costly for them to do this. To the extent that they succeed, it drives our acquisition costs up.
The one other thing I would add about win-back is this. The most insidious thing about it is that the only ones who can use it are the incumbents. If I make a sale to a new customer who leaves the telco, Primus can't call that customer up and try to win them back. Vonage can't do it. Rogers can't do it. The only one who knows it has happened is the incumbent. And why does the incumbent know it's happened? Because the incumbent started with all the customers, and that's a legacy of their monopoly.
