If you're pirating content, you should retain complete control and security over your setup. How does Infuse enforce its yearly license cost? There must be some telemetry at the very least, which is exactly the issue that got Plex into this situation and why people would do well to avoid it (unless of course you're just watching your own legal copies of media).
It's apple only (tvos, ios, and macos). The yearly subscription is for enabling formats and resolutions, I believe. They don't have a server part. They just scan your sources (smb shares, cloud drives, plex, jellyfin, emby,...) and present a library. My setup is Jellyfin (old Mac Mini with ubuntu server) + Infuse on Apple TV as the player.
There is likely telemetry - good point. I assume that such telemetry can be block if you are concerned.
