Along with everyone else here, I don't know the specifics of the "restricted" feature, but features of applications like this often depend on OS support. It's quite possible that this feature depends on something Windows does that the Mac OS doesn't. Or, if they both do, they may work so differently that writing one app for both isn't practical. Either of these situations could, via communication errors as information gets passed along from one person to another (and perhaps "dumbed down" for a non-technical audience) until it finally reaches the end user, have ended up coming across as an Apple "restriction" - even though it isn't one in the usual sense of the term. "Apple prevents us from doing X" could just mean "Mac OS doesn't have the facilities we need to do X, or to do it the way we know how to." In other words, it may not be a deliberate lie.
