This is a pretty ignorant and sensationalist take.
Even if Sony were to purchase Leyou, there is absolutely no indication that SNK would become part of Worldwide Studios or produce games exclusively for PlayStation.
Sony Interactive Entertainment is administered separately from Sony. What Sony owns isn't owned by Sony Interactive Entertainment.
Sony Corp. MAY (if Bloomberg's info are correct, which they often aren't like much of this rumormongering from completely anonymous sources. Remember all the drumming on the Switch Pro?) be bidding on Leyou, but it isn't Sony Interactive Entertainment purchasing SNK.
Sony owns Unties, which publishes games on Switch and other platforms and doesn't have any relationship with Sony Interactive Entertainment.
Sony owns Aniplex which owns Fate/Grand Order, yet PlayStation isn't getting an exclusive FateGO (which would likely be a very smart thing to have to push PlayStation in Japan).
People who don't know how this stuff works tend to identify Sony with Sony Interactive Entertainment. That's not how it works.
