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
You can’t purchase digital media. All you’re allowed to purchase is a revokable license to consume it under some corporation’s terms.
