Bait-and-switch is a form of fraud used in retail sales but also employed in other contexts. First, customers are "baited" by merchants' advertising products or services at a low price, but when customers visit the store, they discover that the advertised goods are not available, or the customers are pressured by sales people to consider similar, but higher priced items ("switching").
Game companies use bait-and-switch by making a product or in game virtual equipment that says it will do a specific task, and then after they release it without testing, change one or more of the effects of the item, usually after you pay to upgrade an item for the intended described effect. Even though the original item may be free, the upgrading costs real money, hence the use of bait-and-switch to describe this act. Terms of service does not exclude the company from changing the product without adequate testing upon releasing it, without any form of equivalent compensation.
