Years ago I was invited to listen to a presentation for a very large, very expensive project. It was rather technical in nature, and the people in charge of paying for it wanted my opinion.
So, after politely listening to the presenters, I gave my opinion. For free.
I pretty much said that the entire thing was shit. It was impractical, ill-conceived, and didn't account for substantial costs that would be associated with supporting it. I ended my observations by saying that the people in charge of the presentation had no business acting as consultants since they obviously didn't know what in the hell they were talking about.
Thanks to my "opinion" the project was dropped, and (luckily) no further money was wasted.
Fast forward to today, and I find out that not only was I blamed for the project's failure then... I am still being blamed for the project's failure now. Apparently it's my fault that the consultants were dumbasses. It's my fault I was smart enough to see they were dumbasses. It's my fault the people in charge listened to me tell them that the consultants were dumbasses. It's all my fault.
Far easier to blame me than the dumbasses.
Ultimately this has -zero- effect on my life. But it still pisses me off.
It's quickly getting to the point where if somebody actually has the balls to take responsibility for their own bullshit, I may die of shock. Which would actually be preferable to dealing with stupid shit like this
