I hate to break it to you, but code is usually written in support of a business objective and does not exist in a vacuum of technological purity... I say this as someone who's written everything from x86asm to python and everything in between for decades. If it really upsets your sensibilities to insert a reference to that business objective in a commit message then I don't know what to tell you...
A business objective is generally translatable to a use case, user story or requirement that can be understood without knowing "Mr. Smith from Company Thingamajig struggles to do x and is willing to pay sums of money to have it fixed". Your developers absolutely should NOT be knowing or dealing with business objectives.
As always there can be exceptions but if this is normal operating procedure for your company I would run far and fast.
