Using the User

To do your product testing.

Microsoft did this with Windows 10 - they offered this for free, and after its users got the bugs out of it, they charged for it. I have one of these myself.

Consider this Digital Camera I bought from Amazon. It was actually made by Gopon (whomever they were) very cheaply - with an inadequate User Manual.

Amazon just came out with this camera. Its users have tested the first camera, and it can now sell the same thing, as a different brand, and pocket the difference. It even has a pink color!
