"Buy now" makes sense because you would be buying a license.
Although I do agree that the distinction between a product with DRM and a license to use a product with DRM does not seem well distinguished. Exactly what you are obtaining should be spelled out, at least in some form of legalese somewhere that you see when you buy the product, not just in some document buried on the website you're browsing.
I don't see any mention of the fact that I'm buying a license on the page. Whatever about the hacker news set, but you can't honestly expect average consumers to pick up on this distinction without a very clear and obvious "DRM for dummies" tutorial. Legalese won't cut it. This nonsense is unethical and dishonest.
