Encrypted content means more CPU cycles needed to decrypt it in order to play it, this prevents older systems from viewing content and reduces performance in newer systems if a user wants to multitask
by the nature of this technology, there will be a bandwidth overhead as it takes more data to create and maintain an encrypted stream of traffic.
the legit user gains nothing from this, they only loose bandwidth and system performance, and through the nature of permission based DRM, is it requires an internet connection in order to confirm that you are not stealing and if you don't have internet or the company that does the DRM or owns the DRM servers, dies, then your content is gone also
imagine spending hundreds of dollars on content and suddenly loose it because the company that owned the DRM servers goes out of business.
companies need to learn that DRM does not stop piracy it increases it because think about this
if there were 2 people offering you the same content; Person A if offering a video with DRM in which you get the content, it only works on their software and their portable devices and the content has to be validated on their servers so if they ever go out of business, the content you paid for is useless.
Person B is offering the same content which will come with no DRM and will be available in any format you want so it can work with any device.
who would you go with?
what these companies need to do is put no DRM of any media or games and instead offer an experience that cant be pirated. Piracy is not convenient, it requires a user to spend time looking for the content, downloading it and scanning it for infections with multiple scanners, and hoping it is the correct content that they spend all day getting
avoiding DRM makes this worth it for them,
the media companies need to make a service that is very convenient and easier to use than the pirate route, they need to make the content available in all popular formats and make it so that a propitiatory program is not needed to gain access to the content.
look at movies, there available for download and also sold on almost every street corner here in NY days before the movie is out in theaters
on the way to the movies, you will pass by at least 10 people selling the movie on dvd. but theres one thing that cant be pirated, the experience, and quality and guaranteed safety of the content, + you can bring in your favorite meal with you to the movies if you put other stuff on top of the food and put it in a bag
when a few hundred million people go o see a movie, can the media companies really think that they don't know about pirating the content, they do, they just rather go to the movies to see it
