Often different testers will find the same bug, or multiple bugs have a common cause. <br>Also someone's role is to constantly review and prioritise ("groom") all outstanding bugs so developers focus on the highest priority ones first. Usually that prioritisation is done by someone who has responsibility for the product, so is not a good task for outsourcing.
