User confusion is a real thing. First stage of this is when presenting a download - how does an average user know which of the 3 or 4 binaries you offer to download? Then a year later the user gets a new computer and migrates everything to it using Migration Assistant. The platform specific binary he downloaded from your website no longer runs, and he assumes it’s because it’s broken, or the new computer has a new OS, or he has to buy a new copy for the new computer. Another potential problem would lie in a user copying an app to a second computer with a different architecture. Lots of reasons to distribute fat binaries if you’re not in the App Store (n which case the OS can/will auto download the correct version upon migration).
