I don’t think their goal is to become the next Reuters. as far as I can tell, the articles on the website are posted by one (1) person, and they’re free to express themselves in whatever way the want.

besides, for me at least, the phrase carries a specific meaning. it’s a self-deprecating quip, an acknowledgment that what they did wasn’t some super serious journalistic work, given that it mostly comprised of sending Mozilla an email, and doesn’t warrant using something that would indicate more extensive journalistic work like “I did some digging” or “I investigated”.
