When you go to the store and purchase something, it’s easy to understand that the item you purchased is the product.
On the other hand, when there is a free product or service, in most cases, you are the product. Companies offering free services are using you for the data you provide. Whether it’s Facebook, Google, Pinterest you are providing them data, based on your actions, which they use to monetize.
There is nothing wrong with being the product but I do believe it’s important to know what your role really is.
Have a great day!
