Blu-Ray kind of shot itself in the foot by having an insanely restrictive copy protection (AAAC) applied, which made watching movies on a PC/Laptop all but impossible, especially offline (I traveled by train a lot in 2015)*. It was obviously broken fairly quickly, so they added BD+, which was also broken within 4 months.

It should be regarded as a cautionary tale against any form of copy pretention, but they sell the keys to the hardware suppliers, so I guess making the customer have a worse experience still paid off.

*No, paying PowerDVD a yearly ransom is not a valid solution
