It's a bit clickbaity to say Intel "lost" the PlayStation business when they didn't have it to begin with.
Sony has been using AMD CPUs for a couple generations of PlayStation now. Moving over to Intel would have screwed up backward-compatibility, adding a ton of work and striking a huge blow to efficiency if anything were going to be backward-compatible down the line and also thrown that monkey wrench into the works of any developers publishing for both generations during the switchover. The article touches on this a little bit.
Intel would have needed to present some magically miraculously sweet deal for Sony to even consider switching, and especially when Intel is doing generally crappy I can't see that being an easy thing for them to figure out.
