The WordPress developers have chosen to use the bbPress software over phpBB because they developed bbPress. bbPress is a bare-bones, fast, forum system, and is a work-in progress. It supports registered users, categorization, tags, topic history, resolved/un-resolved status, and a search engine (when properly implemented).
The official way to contact the WordPress.com support team is through the "Feedback" tab in the Dashboard of your WordPress.com blog, or on the WordPress.com forums.
