Yes and no. Naughty Dog was bought by Sony back in 2001 and the God of War games have been tied to multiple studios and developers over the years. Plus keeping the only AAA baseball game on Playstation an entire generation was a dick move too. They also don't let Spiderman be on any other platforms.
There are other Developers for Sony exclusives that have been tied to other platforms too. Sony just publishes them.
I don't care either way. I have a PS4, and XSX, a Switch, and an Oculus Rift 2 so I'm not really going to miss out on anything at the moment, but this is just the way the industry is, and it's hypocritical to call out Microsoft, but defend Playstation when it comes to hoarding intellectual property. At least Microsoft has the Xbox and the PC.
