There is certainly a fair bit of army and navy roping themselves off from each other. However, this is them valuing their own independence and is more an act of bureaucracy maybe mixed with a bit of pride than it is an act of hostility. Uchi-soto (Insider/Outsider) has always been a little stronger in Japan than elsewhere and this is where we are seeing the effect, but that's not the same as hostility. And if you want to point to what may be apocryphal anecdotes, you'll have to look and deal with the times they did manage some cooperation as well.

>Commerce is about satisfying the majority of the market

Commerce is better described as maximizing the market sufficiently satisfied that they'll continue buying your product.

So yes, if it is between A which is 80% and B which is 20% well in the end they'll choose A. However, at least for the moment, even if A is the majority they can be sufficiently placated using German ships, Italian ships, maybe later French ships. They are only somewhat interested in seeing Allied ships. For the moment it is not a deal breaker or even major minus if they don't.

Which leaves their priority towards placating B, who might indeed see it as a deal breaker if Allied ships are inserted. Though it may be only 20%, there's no need to risk losing their business yet.
