If you’re paying for it, then you could argue that you aren’t “stealing” it. How are you (or at least the average person) suppose to know that the steaming service you used got their content illegally? This way, all of the liability falls on the streamer rather than the consumer.
I upgraded to the OLED model when it came out. The screen looks much nicer, has a faster refresh and longer battery life. I definitely recommend it over the original, but it is a steep price when you already have one that works fine.
