This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. Open Source software is software with source code that anyone can inspect, modify or enhance. Freeware products can be used free of charge for both personal and professional (commercial use). A fat binary can contain an arbitrary number of supported architectures, a few years ago it was not uncommon to have iOS libraries compiled for multiple ARM flavors (ARMv7, ARMv8, ARM64) and Intel flavors (i386, x86_64, for the iOS Simulator).Freeware programs can be downloaded used free of charge and without any time limitations. You can see that the binary contains code for both the x86_64 and arm64 architectures. Volumes/Discord/Discord.app/Contents/MacOS/Discord (for architecture arm64): Mach-O 64-bit executable arm64

Volumes/Discord/Discord.app/Contents/MacOS/Discord (for architecture x86_64): Mach-O 64-bit executable x86_64 Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64 Volumes/Discord/Discord.app/Contents/MacOS/Discord: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64 When you download the Discord app and just mount the disk image, here's what you get when you run file on the main executable: $ file /Volumes/Discord/Discord.app/Contents/MacOS/Discord The OS then picks the appropriate part for the current architecture at runtime. Basically, the compiler generates executables for multiple architecture and then combines them into a single file. Apple calls this a Universal Binary and it was already used in the PowerPC to Intel transition, and then again in the Intel to Arm transition. On NeXT-based system such as macOS (and all other Apple OS's), a binary can contain code for multiple architectures.
