I'm not sure how illegal copyright violations really are, given that all major tech companies are doing it. DDoS attacks, on the other hand, are pretty clear-cut.

I also think "but they also do that other crime" doesn't help their case.

I think the DDoS is clearly problematic, I just don't think it's problematic because it's criminal.

It's problematic because it's childish and pointlessly degrades the user experience.
