[Tolriq]

Tolriq, you linked to literal maritime piracy. But fortunately that wiki article includes a redirect to, you guessed it, copyright infringement, which is what piracy with regards to content is.

Yes on purpose, glad you notice You wrote "Piracy is generally defined as the sharing, copying, or performing of copyrighted content from one person to another person via the internet" this is not really the case, this is a very small subset of the term. Yet a valid one for some.

https://www.gnu.org/philosophy/words-to-...tml#Piracy for GNU piracy is exactly this definition of maritime acts, and clearly says that non approved copy is not piracy as piracy is something violent like murder. This does not match your definition, yet fight for GNU point of views for other things.
Illegal copy is not piracy for them, so all addons that permit access to illegal content are not piracy They allow to bypass rules made by providers, the exact same thing that other addons on Kodi repo does.

So as I try to say since I jumped in this thread, we are very far from black and white discussion, there's point of views, there's opinions, there's laws, there's TOS. Youtube addon and Twitch addons are illegal from legal point of view, you may tell it's not piracy because the content is accessible on those site, but the addons does permit the bypass of the TOS. This is the same infringement as DMCA, the content is here but law does not permit you do use it like you want.
Point of view, black / white or grey? Not my skill to judge.

I just continue to say, that I see way too much things written like facts, about being white, others being black. And everything being simple. This is not the case at all.
