Those long lists are mostly full of everything but consumer electronics: semiconductors, gaming studios, movie studios, TV networks, music labels... heck even real estate is on there. So they kinda have a point when it comes to consumer electronics (which is what I think they meant with "customer market").

The current Sony has little to do with the one from the 80s, 90s or even early 2000s... In addition to the PlayStation they are strong in imaging (photo and video cameras) I think, but little else, and those products no longer have mass appeal (they are getting high-end- and pro-focused). Vaio, Xperia, Bravia, Walkman... gone or on life support. Browse their site and there's a handful of products left, as good as they might be (which I don't know).
