You're still conflating the success of a tactic in furtherance of a goal with the success of a goal.
> All the Unabomber accomplished was a lifelong stay in prison, the death of three people, and the injury of dozens more. By your strong metric, neither approach is successful. By a weaker metric, an organized campaign that doesn't include bombing people is partially successful.
Maybe the Unabomber's ultimate goals will bear out (I sincerely doubt it for reasons I have expounded upon elsewhere in these comments), but even if they do, he didn't pull it off.
If, 300 years from now, history remembers this era as a dark time of bad technology that humanity grew out of, the Unabomber gets remembered as this struggle's John Brown, not this struggle's Abraham Lincoln.
