Poor editorialized title.
"Editorialized" implied deceit was intended. It looks to me like the submitter was trying to be descriptive.
The very first item in the feature list is
> Easy to use, with a game inspired menu system.
that said a enjoy looking at code for projects that are multi os so cheers for op.
"Poorly described" would be correct. "Editorialized" does not mean what you think it means. See my previous comment.
Editorialized here simply means applying editor-level changes to the title of the website to express an opinion. No deceit is implied. It is against HN guidelines unless the title is unclear or does not fit.
That's all.
They could have described it as "game-like design" or something else.
It was the submitter's opinion that "gamified" was an accurate description for this page instead of using the actual title of the page.
So while "editorialized" is a little formal, it is correct.
Reporting on controversial issues is often editorialized, which may be where your feeling that it relates to deceit is coming from.
That does seem obviously like an opinion, however there are some things that don't seem like an opinion that can still be considered an opinion.
This fits a whole class of headlines, which are described as editorialized, some of which seem more opinionated than this and some which seem less opinionated. I'm not sure whether it's better wrangle the use of opinion and the definition of opinion to make these satisfy the dictionary definition of editorialized or accept that the use of language has evolved and it's better not to be overly prescriptive.
