It’s wild how many people are buying into “it’s not a license” marketing fluff, when actually acknowledging it as the license it necessarily has to be and explicitly granting rights would be way more in the consumer’s interest.
The fact that they’re DRM free is good. But a vague marketing statement that “you own it” without actually clearly granting rights in a license is not good. (There might be license terms somewhere on the sites he’s referring to; I didn’t check because it isn’t actually relevant to anything.)
