There are people who suggest that a DDoS is just a 'digital sit in', a legitimate way for someone to air a grievance, if they think the targets (or world) haven't paid them enough attention.
This view makes DDoS seem more normal or even romantic/heroic, and spreads the tools/know-how more widely. So, pulling off a DDoS becomes a more plausible and attractive aspiration, for a larger set of surly people with marginal reasoning skills and destructive impulses.
The DDoS tactic should be rejected as dishonorable censorship and vandalism, no matter the cause under which it is launched.
