If you read Section 1798.140 of the Civil Code: “Commercial purposes” means to advance a person's commercial or economic interests, such as by inducing another person to buy, rent, lease, join, subscribe to, provide, or exchange products, goods, property, information, or services, or enabling or effecting, directly or indirectly, a commercial transaction."

Basically SB690 means that a business can spy on us including our most private data and use it for anything that makes them money like selling it to data brokers or to the government.
