I think it's just about disagreement and in order to empower themselves the attackers vilified and demonized the developer. It's not so different from the way people will vilify (rightly or wrongly) an entity like the RIAA or a country such as Libya or a profession such as law, or a person such as any ex-president. It's easier to disagree with someone who's been vilified beyond recognition, rather than have a discussion on the factual data.
I think this is what's happened here. The humanity of this person was removed and reduced to repugnant caricature which made it easier to pile on the fun. Yes, people do this every day.
It's not right, but it's human nature. Still, that's not a reason to ignore the issue. It's probably related to or one of the reasons why women avoid tech. Those who pursue it have to be so steadfast that they can survive all the sexism and ridicule. The closest men come to this is straight male on straight male sexual harassment. http://www.thedailybeast.com/newsweek/2010/01/12/abuse-of-po...
Also, my take-away from the article was not an attack on the interwebs. If anything, the community was blamed - not the method of communication.

But, we're human, and we can't have nice things.
The world is filled with trolls. It doesn't matter what attributes you possess, thick skin will serve you well in life, and that will always be true. If you're fat or skinny, beautiful or ugly, rich or poor, you're going to get shit on, berated, harassed, and so on, at some time or another. Almost any sharp edge in any direction, about any topic, basically, results in blow back. That's not to say all scenarios are created equal.
You can hardly name something that isn't divisive these days. And now you know what nearly everybody thinks about everything courtesy of Facebook, Twitter, et al.
Mediums change, but trolls remain the same.
