Even Century Old Records Had Restrictive Licensing
natch writes "While rummaging through some old records at an antique store I found some turn-of-the-century Victor Record Company pressings. The label on the back laid out the terms of use, something similar to an EULA. In today's modern world of RIAA lawsuits and DRM, it's interesting to note that similar tactics have been in use by record companies for over a century, restricting your right to use what you purchased. The label clearly states that unless the record was sold for at least one dollar, there is no license to use it."
Where is it coming from? It's right in the bargain that copyright represents. The creator of the work gets the exclusive rights for a period of time, protected by the law, and after a period of time the work falls into the public domain.
In other words, the sense of "entitlement" exists in the same sense as if I said "If you pay me first, I'll give you something later", or vice-versa. i.e., it's like a contract, and the public deserves to be paid their half after granting a monopoly for a reasonable period of time, in advance.
The way you're talking, it's as if you walked into a restaurant, ate a nice meal, and then act surprised at the request that you pay up. I suppose if you had to sign a contract to eat it might be more obvious, but the bargain does exist.
