Brought not created. Insomniac can't make Spider-Man without Sony's money. Sucker punch couldn't have made infamous and sly copper without Sony's money. Returnal and demon souls would not be possible with the company living paycheck to paycheck relying on Sony money. Kojima needed Sony's funds to literally start a studio from scratch. We have seen what happens to studios who don't get funding. They shut down or stop making AAA games.
A company with $8 billion in revenue wasn't hurting for funding. Yes, in that case the content is bought to lock out access. But In the case of forza horizon, gears of war 4, titanfall 1, demon souls 2009, infamous 2009, kz 2004, heavenly sword 2007, death stranding 2019, returnal, and nearly all other Sony owned IPs made by independent studios, that content wouldn't exist without first party funding because no one else was interested in funding them. Cod, elder scrolls, fallout, doom and starfield are the biggest ip in the business. They have existed for decades without first party funding.
