I am not sure anymore. With twitter and cancel culture around? I can't imagine the legal fees and terrible optics would NOT be worth this. Maybe if this person was Sony with deep pockets. But there is no reason for Bose to chase some app that makes $50 a month.
The problem is the name: it's too close to the protected mark. You need to enforce your trademark or else you weaken the protections afforded by it.
I doubt it would come to a lawsuit though unless the developer resisted. More than likely Bose will send a C&D and the developer will comply. It's a fairly reasonable request in this case.
