I haven't really thought about this until just now, but how does the "no interpreters!!!1!bang!one!" thing work with formats like TrueType, OpenType, H264, PDF, Postscript, and others? Is Apple "turning a blind eye" to the interpreters for formats they want to support? Do they frown on these interpreters as well? Are developers limited to whatever support for such formats the Apple SDK provides?
I guess I'm only asking because a lot of formats require an interpreter of some kind. I can't imagine that Apple really wants to restrict third-party support for all such formats. How could they ever justify the loss of content?
