An acronym is a specific type of abbreviation formed from the initial letters of a phrase and pronounced as a single word. I was being more specific. And the ones you are pointing out are from the header.
> An abbreviation whose expansion is provided the first time the abbreviation appears in the content
Content is the main body of the article (press tab ones you land the page, it will take you to the main content if you don't know what that is), which contains only one Acronym, “SC 3.1.4” → which is a link that take you to a place with its definition. I don't understand what you are fighting over. But I'm not going to reply more to someone who defends people who do not know how to write articles that are more friendly towards the reader.
