That unfortunately is the north american way of business that is being forced onto the rest of the world. Why pay for research in advance and risk all the money when the product turns out to be harmful when you can instead just release it, let others pay for it and do the research for free at the same time? As long as there are sheep willing to follow others instead of using their own head this unfortunately will continue.
Premature releases are also a thing in the music industry but obviously with a lot less potential of harming your health/environment.
