Whether that's the case or not, it's not going to cause a person to kill himself out of the blue, and comments like this probably make the situation worse.
The thing with suicide is nobody ever really knows exactly why any given person does it. Sometimes it's just a total mystery. Even if somebody says why they're going to do it before they did it, such as a suicide note, it's often not the truth. Look at the way some narcissists threaten to kill themselves if a person they're fixated on leaves them. The person leaving them isn't fundamentally why they'd do it, rather it's because they've got a bunch of other unresolved issues, and it may not have even taken much at all to just nudge them over the cliff. Events like this are the just the tip of what is often a very large iceberg.
I say this as a person who has had somebody close to me put two bullets in his head while I was within earshot. There was a major particular event surrounding that, but the truth is he had already made multiple attempts in the years prior, so blaming it all on that event or the people who caused it seems pointless.
This is easily the case with Aaron Schwartz given his past. I definitely think this is the case with David Ginder given what I'd already seen about his past long before that made slashdot. In the case of all three of the people I mentioned, I believe there may have been an acute martyr complex. Nobody can really say for sure. But news media and social media love martyrs. Which may encourage more martyrs. See also: Columbine effect.
