You guessed it right, only CONVENIENCE of prebuilt images are sold, but due to Apple's developer account restrictions, it's actually better to use the official version if you don't want to spend $100 to build the ios version.

In addition, there are indeed two better-known, unofficial patches with paid restrictions removed, one is an experimental version by a third-party developer, which is submitted upstream after testing the functionality, at github.com/siyuan-community/siyuan, and the other is a patch that simply removes the paid functionality. It's at github.com/EightDoor/siyuan.

Also, there was actually a pr from a community developer to add digital certificates to ensure that unofficial packaged binaries wouldn't use the official cloud service, since the plugin bazaar uses the official cdn, which is actually not a small amount of traffic cost, but that pr was rejected.
