Elmodiddly: Why was DRM made? The answer, apart from ridiculous immature respnses such as "To make us unhappy" etc, etc, is quite obvious. DRM was designed to help stop or lessen piracy.
This was why DRM was initially instituted, but as the technology surrounding piracy, as well as the overall market, has shifted over the years so have the reasons for the use of DRM. Something essential to recognize about DRM is that it only limits what people can do with legitimate copies of software. I'll repeat that because it needs to be emphasized: DRM only limits what can be done with legitimate copies of software. A pirated copy that has had the DRM bypassed is naturally under none of the constraints imposed by the removed DRM. Another essential thing to recognize is that DRM as a security model is fundamentally vulnerable. At its heart DRM is cryptography but where potential attackers are handed the encrypted data, the cipher, the key, and the plaintext. These last two are buried under layers of obfuscation, but obfuscation is absolutely worthless as a security measure against any determined attacker. The end result of all this is that any DRM scheme can be broken if someone wants to break it.
Now, the fact that all DRM can be broken was not so much an issue back in the day when we were seeing dongles and bad sectors on floppies. This was because piracy at this time was mostly limited to people with legitimate media looking to install it on multiple computers (friends' computers, relatives' computers, all the computers at their company, etc). You didn't have to stop everyone from breaking the DRM, you just had to make it difficult enough that it simply wasn't worth the hassle for most people. Broadband becoming ubiquitous and the development of decentralized distribution protocols (e.g. bit torrent) changed all this. Now all that's needed is for a single person to break the DRM and put up a torrent, and suddenly any drooling moron can get a copy with the DRM already broken. In short, the fact that DRM is fundamentally broken as a security model now means that it is absolutely ineffective at preventing any meaningful amount of piracy.
So why do we still have DRM if it is ineffective? I believe that part of it is that many in decision making positions still haven't been clued into this fact, and combined with control complexes and the inclusion of DRM almost being something of an industry standard it remains around simply as a relic that no longer serves a purpose. But as I said, I believe this is only part of it. Recall the first essential thing to remember about DRM: it only limits what can be done with legitimate copies of software. What follows from this is that we're seeing DRM not being included to stop pirates, but to limit what people who purchased the software can do with it. The ability to resell the software is a big thing some companies are targeting, with the ability to backup media also being targeted to a lesser extent. DRM now serves as a way to strip away rights with technology that people would otherwise have under the law.
If you're still reading at this point, thank you, and allow me to summarize: piracy can no longer be stated as a rational reason for the continued existence of DRM.
fuNGoo: All the people who are wanting to get rid of DRM are only looking at the issue from their own perspective. Which is fine, if you just want to be another whiny internet voice that will be mostly ignored by the people that matter. But if you're serious about debating the need for DRM, you have to admit it's a lot more complicated and nuanced than just crying "Death to DRM!"
The call to get rid of DRM makes sense from both the perspective of customers as well as the perspective of software developers and retailers (something that's been recognized by GOG, numerous smaller developers, and to a lesser extent Stardock). From a customer's perspective the reasons for ditching DRM should be obvious. From a developer/retailer perspective the reasons to get rid of it are that 1) it doesn't prevent any meaningful amount of piracy 2) it costs money to implement and 3) it has the potential to decrease sales and drive away customers. If you still want to go into what you consider to be the complicated and nuanced aspects of DRM then I'd be more than happy to discuss the matter in detail, although I'll give you fair warning that DRM is one of my favorite subjects to debate and rant about.
