No, because it's subjective whether your interpretation of "fiduciary duty" precludes them from developing an OS. I think it does not, for example.

Yeah, goals are subjective too.

Words do mean nothing, they are pointers to ideas. And for you "objective" points to a different idea than it does for most people.
