Hardly pendantic to point out the obvious truth. Headline is a lie
Good to know I suppose.
It's just not Open Source according to the OSI people who believe they own the term. They do not hold a trademark on the term.

The term "open" has been used as a weasel words in the industry before OSI and "open source".
Off the top of my head: "The Open Group", "Open Software Foundation", "X/Open", "Open Look", "OpenStep", "OpenGL", "OpenMax", "OpenType", ...
It's best to use more specific terms like "BSD licensed", "MIT licensed" or "Copyleft".
Or FOSS. "FOSS" is a thing because open source isn't necessarily free due to the conflation with source-available.
