Well its Videotron's right to service and cater to whomever they wish. If its the Francophone market, so be it and hence, decisions like dropping Peachtree.
As for the Bell argument, been there - done that. I was with them a few years back and switched to Videotron because the HD channel choices and equipment was better. Also, whether true or not I thought cable internet was faster. Today's a totally different situation and whatever advantages Videotron had (or what I perceived as advantages) are gone. In fact, I think Bell is ahead with HD channel choices.
I never had any issues with Bell when I was with them. Sure, things could have changed but I haven't heard any negative talk from people that I know who are with them. This leads me to believe that this is similar to the Vista complaints. I read and heard so much about what a POS Vista is and how incompatible it is, etc, etc. Yet I've been using Vista since it came out and must say it is one of the most stable OS's I've ever used. Had many more problems with XP & 2K and would never go back to those.
Bottom line is that there no longer is any significant reason or advantage to stay with Videotron. The sad thing is that they really don't care if you leave.
