Sometimes you need to use some common sense rather than keep quoting out of context.
The point is /was, there is nothing responsible about declaring to the world a vulnerability or bug when it has been fixed. I know that last part is what you find hard to understand, so I’ll elaborate by stating the obvious: Rather than declare it as a bug after it’s been fixed, the responsible thing would be to announce the finding and fixing of the vulnerability / bug.
The way the parent article was presented (and the dev objected to) was the insinuation that the bug was still not fixed. But of course, you are more concerned about the appeal to authority by quoting wikipedia rather than applying some (usually) common sense.
