It might just be my experience dealing with Bell when we had ExpressVu before becoming cable cutters, and Shaw's Internet service when I was growing up.
I also hate the things Bell has tried to do through the CRTC, like that whole Internet thing with smaller providers using its pipes.
I guess it's a principal thing.
EDIT: Another example... I used to always choose Famous Players for movies. I avoided Cineplex. Then Cplex gobbled up Famous and I started going to Landmark. I should be able to choose where I consume my content.
