Economic theory suggests that changing the output of a single supplier does not affect overall prices in a competitive market like this - that’s very different from oligopoly or monopoly situations. I would highly recommend “Basic economics” by Thomas Sowell for anyone interested in a good overview of these kind of issues (audiobook also available on YouTube, I believe)
