I don't really care what everybody else is doing, I'm just glad I can still buy a NAS and fill it with 10TB drives if I wanted to. I don't even have to search to hard to find them. It probably even pretty easy to make those drives public.
Indeed, I have a NAS full of my own ripped media and find myself using Kodi more often than the streaming services (I pay for Spotify, Netflix and Amazon) just so I can watch whatever I want to watch rather than whatever they happen to have available at any given moment. Another bonus is it's all ad-free.
Economies of scale work against you. If the consumer hardware market shrinks, there will be fewer players on the market. Fewer players may lead to erratic supply and/or monopoly-driven price hikes (see e.g. pharma). So you should care, on at least some level, what everybody else is doing.
