I think Michael was going for the humor of the situation but the article was quite condescending from a reader's point of view, especially since Michael is making the mistakes of these devs more public than it ever should be (I can't believe you included his name, poor guy).
I've been on many different mailings lists and new comers almost always ask what seems to be trivial questions (I've done this, I'm sure). But we need to be welcoming if we want to foster a friendly, open environment that everyone enjoys working with. Or everyone will leave and no work will ever get done.
In regards to the Silicon Motions developers, REALLY? There are hundreds of git tutorials and while I do appreciate your open-source work A LOT, please submit meticulously written code - most everyone else does, you are no exception. Then we can avoid these situations. Hopefully, we will be able to laugh about this situation over a beer someday.
Good luck to you!
