I hate Apple's app store policies as much as the next guy, but does this mean I can make malware that plays music and Apple has to allow it in the app store?
And btw, those apps that the app store is full of that trick you into a $80/month subscription aren't malware?
I release an app that BOTH plays music AND is malware. Under this law, Apple can't ban the app (because it's malware) because the law prevents it to (because the app plays music, competing with one of Apple's apps).
Bonus: you haven't read the Japanese law in the original Japanese legalese*, just an english summary.
* And since it's in legalese, you probably couldn't even if you spoke some Japanese.
Thankfully, our legal systems are much better equipped to deal with ambiguity like this than I think you are proposing.
