And why would they feel the need to announce to the world that they change brand if the don't get paid? Hello, I switched to Sony I feel it is so important that you know it so I am having this press conference!
I don't know about Bob Krist's specific example, but if I switched from iPhone that I have been using for over three years to Android, and felt it was a significant upgrade, and I had a blog- I won't write about it. Because I would be excited about it. People express their feelings. It's natural.
Once again, can't comment on what Bob Krist's incentive might have been. But he did seem excited...
I think you have identified the problem.
There are some members of this forum who treat the publishing/linking of an opinion as a provocation. That's what I don't understand. There are many many opinions I don't agree with, but I never consider them a provocation.
If the members really did not agree with the opinions in the video, would not the best action be not to respond to the thread? After a few hours/days of no action, the thread would die away.
I think it might be a combination of two things- firstly, buying a certain item causes the buyer to identify his/her intelligence, judgment, knowledge etc. with that product. So if that item is vilified, the buyer considers those attributes of his to be questioned. If you think this is too much, you should see the Apple forums. Secondly, there is something about anonymous internet forums, where people feel it is okay to vent their frustration and anger to a nameless, faceless audience or towards another person, being nameless and faceless himself.
