It's unclear why the author of the article decided that the word 'mistake' deserved the scary quote treatment.
That may not be malice, of course. It could just be incompetence (someone running an automated scanner and not verifying that the results are correct), someone trusted with a job they're not capable of doing, or maybe it's just Mozilla pretending someone reviewed the addon while using shitty AI like ChatGPT to do all the work.
The email even directly links to resources that are supposedly "minified, concatenated or otherwise machine-generated". That's simply not true.
That should be obvious, honestly. The extension is a threat to the reviewer's paycheck...
Obviously this could all just be incompetence. It's just a convenient excuse to do some more Mozilla-bashing, (lack of) facts be damned.
Not that any of this excuses the experience Gorhill had, of course.
