I've worked in a number of different companies. All had quite substantial IT spend. All employed very bright people. Of the 4 most recent, two had the habit of being flexible with their IT rules for members of the boss class. 2 had zero flexibility for anyone.
One of the second group were really controlling with their IT. Whilst that level of control pissed me off (a bit), I had to admire their persistence.
I imagine that Sony were of the flexible sort. Flexibility is nice, but.....Leaves all sorts of doors open.
