Upvoted you, but the answer is no, this might be a very smart move by them depending on their strategy.
If they want to lock down market share, this is a great play to build loyalty, especially if there's new competitors directly in the space (other broadband) or substitution products (3G, whatever). They might have run some numbers and figured X% of their customers would get poached if they remained at high prices, and it was better to preemptively lower prices and get a lot of goodwill in the process. Market share + loyalty. Max short term cash isn't always the best goal.
Edit: Especially in a business that's high capital intensive with low marginal costs. Furthermore, doing this might dissuade other companies from coming into the space to compete. Strategy can get complex, especially when you've got millions/billions already invested infrastructure.
