No, he's "excusing" it because Microsoft will at least release some of their games on other platforms. At the very least, you'll get Bethesda games on PC as you've always been. If Sony bought Zenimax, all of their games would be exclusive on PS5. You maybe would get them years later on PC, but you wouldn't get them on Switch of Series X ever. Already, Microsoft is better in this regard than Sony as seen with Minecraft, Ori and Cuphead. His comment on Sony being arrogant is that, yes, they are being arrogant and this move should make them realize you can't coast for the next generation. You've been putting words in his mouth.
Also, let's not ignore the fact that many Sony fans in this thread said they'd love for Sony to buy Zenimax. So it was never about walling off developers. It was about someone else besides Sony walling off a developer. Your post in this thread are just sour grapes.
I'm not putting words into anyone's mouth, he actually used the massive buyout of Zenimax as a MS move to wake-up Sony on its arrogance, to white knight MS, and that's beyond absurd to say the least.
"Sony has grown to near 2006 levels of cockiness again and need a wake up call, if it takes Zenimax being walled off from PS to wake them up, so be it."
He is openly fine with those games not coming to PS, and acting as if MS is doing it to wake them up from anti-consumer behavior and cockiness... just wow.
