I think the saying is oversimplified (or else, chrome isn’t a product but a byproduct). It makes a company to make the complement of their product cheap or free so that people can use their product more effectively. Google Search and Ads rely on people having a browser. Similarly, Apple’s Phones and laptops are benefited by including a good first party browser. Imo, a lot of technologies are better as free byproducts of monetized technology than as being some company’s products: there are endless lists of great technologies that never found a market or disappeared post-acquisition.
