You're forgetting the effect demand has on prices. Studios all pulled their content from Netflix and said "fuck you, pay us". People paid, so here we are. Had people said "No, fuck you! Put the content back on Netflix" then we'd still have $15 for everything on one platform. There was enough demand for companies to sell their products. It's not competition when each service has different offerings.
