I thought you cancelled?
Telling a company that you want to cancel because you simply can not work with them due to their dishonesty and shady practices, and then not following through with your threat is a bit dishonest.
I really don't see the problem. A lot of industries use loss leaders or provide a product or service at a lower price, with very little or no profit, in order to build a client base.
It's possible, and i'm only guessing, that Shaw used the lower price to A) reward people that were tolerating the early adopter bugs, and B) to ensure that their army of Gateway installers were booked constantly.
Getting people to switch to a new product can be daunting, especially with large up front costs.
Once the saturation was at a comfortable level for them, they terminate the loss leader.
Often in electronics, by the time the saturation is complete, the cost of production has lowered, either availability of parts, or efficiencies that are learned. If those lowered prices aren't realized from Arriss to Shaw, I see no issue with them setting their price accordingly.
I should note, I was an early adopter, I bought at the original price, and then received the credit. So perhaps i'm biased. However, I also sat on the phone with Tech support for 2 hours trying to solve the original VOD issue. I missed plenty of TV shows that the box chose not to record.
It's not a god given right that technology can only drop in price.
