I’ll go straight to the point:
- Piracy is useful to bypass regional frontiers and access to censored content
- Piracy is helpful to watch content without supporting it if you consider it not worth of it
- Piracy might be helpful for content preservation and survival
- Piracy is useful to ACTUALLY evaluate whether to spend money on some digital content or not
- Piracy is sometimes the only way to actually own DRM-protected content
I completely agree with you but would go one step further - piracy is not only “not immoral”, it is ethically necessary. Without piracy the hard work people have put into their creations (e.g. for the Nintendo WiiU/3DS) could vanish at the whim of one small group of people (in this example, Nintendo C-level execs). Of course there are other reasons too. But this alone is sufficient IMHO.
