For example, I recently went through several lists of underrated (i.e. not the megahits like Ghostbusters or Indiana Jones) movies from the 80s and 90s and I'm hunting them down and watching them. Of the seven movies I watched this past couple of weeks (About Last Night, How to Get Ahead in Advertising, Nothing But Trouble, Other People's Money, The Wrong Guy, Top Secret, Used Cars), ZERO of them can be found on Netflix or Hulu. Five of them can be rented individually from Amazon Prime at $4 a pop, but aren't included in their prime subscription that I already pay ~$100 a year for. That's the full extent of how you can get access to these movies from subscription services. I could have just stuck with what subscription services offer, but if it's not something new the selection gets increasingly worse and worse.
Is that what you want the future to be like? Where these movies might as well have disappeared off the face of the earth because no one can get ahold of them anymore? Because that's the direction we're starting to go in with more and more things going digital only and subscription only.
I used to work in the video game industry, but I have almost nothing to show for it outside of some trailers on Youtube, because almost all of those games were released on digital channels and are no longer available to download. I had two games on the Wii Shop and the Wii Shop is now closed and the company is defunct, so those games are gone. Another on Xbox Live for 360, and a couple of Xbox Indie Games that you can't get anymore because they killed the service. The only game you can still get is Neverland Card Battles on the PSP, and that's because it was released as a physical game.
You can still also play my Flash games I did before I got into the industry, at least until browsers kill Flash off entirely. There was a whole thread on HN recently about how we're about to lose a whole decade of culture from Flash and how one guy is trying to preserve it as best as he can.
Not being able to own the media (even if only in digital form) sucks, because companies can't be trusted to always remain solvent, always have license agreements in place, and always care about keeping all the content available for people to get. If you don't care about the content, then you probably don't care that you only get some access to some stuff some of the time, but for those that care about the time and energy that creators put in and want to experience and share those things with people that may have missed it the first time around or whole new generations of people, this current trend is terrible.
That's actually one reason why I shifted gears and started designing board games the past few years. I have perfectly good and playable copies of board games that are 60 years old now, decades after the companies have gone out of business. I won't have to go through extra effort to make sure that people can still have access to my board games long after I'm dead.
