Whistleblowing is not the same as hosting pirated material.
Now you have a pointless thread five deep.
The premise was that these services didn't actually perform the piracy, its users did. Kim Dotcom played both sides of the field, much like how social media platforms are right now with the whole "we're not a media company" but wanting all the profits of providing services that those companies do.
I'm not saying I agree, but it provides context as to why people felt Kim Dotcom was a hero.
