You don't know anything about film, or storytelling for that matter. The hackers in LFoDH were the antagonists. Without them, there is no movie. The hackers in transformers added nothing to the plot, or the story, or the film. They are not comparable.
If you are talking about the hackers that were killed in the beginning, it sets up a major facet of the plot that brings in the side-kick. Both had a great deal to do with the plot. Also, instead of having 20 minutes of screentime wasted, they had 1 minute of screentime used well. I honestly don't see where you draw comparison. The rest of your list is as equally flawed, and only goes to show you don't know what the fuck you're talking about.
Mhmmm.
