I think we could do a lot worse than anecdotes, but what I find weird is how the anecdotes on HN are always so smug, like this one. "Heh, my old co-worker thought my 'little hacker buddies' couldn't hack his website ;b Let's just say they put quite a dent in it heh ;b."
Bit of an eye roll.
Both are equally derailing. In this case, I would much rather the comments be about the actual OS in question or the trend of big companies crowdsourcing security (penetration testing).
These anecdotes provide societal context to the story. Why would Microsoft get the public to harden their product? Surely they have enough resources to do it themselves right?
Because many eyes make light work. Some people would obsess over trying to hack this OS, putting in far more effort than someone paid 9-5 to do it.
Look at this story. Some guy, who honestly seems to have pretty questionable judgment did a thing and it was a bad idea.
What does that really have to do with this challenge from MS about a custom version of Linux? I would say almost nothing.
