I believe this is a strawman. The issue at hand is political issues that are explicitly irrelevant to the mission of the company.
Issues that are relevant to the company should be discussed and potentially acted upon, if that furthers the agenda of the company (and not just some irrelevant political agenda that you might be passionate about).
Naming something as political can be used to shutdown conversation that can and should be happening in a company.
Let's get concrete with this:
Do you feel like a soft drink maker has an obligation to disengage with countries that have set up systemic discrimination and regularly violate human rights conventions?
It really doesn't seem within the mission of providing the world with sugary carbonated water.
It's hard to imagine cutting ties with a country due to disagreement with how they treat their population as non-political.
And yet 34 years ago this happened:

But wait you say: it's just a prudent business decision because the economics were against them and it was a "PR" win.
It doesn't matter. It's political.
This is an inherently political statement:
“Our decision to complete the process of disinvestment is a statement of our opposition to apartheid and of our support for the economic aspirations of black South Africans.” -Donald R. Keough

EDIT: why did you assume it was a decision made solely by leadership and that employees or other stakeholders did not have a publicly held opinion?
Was my assumption wrong? Did the leadership of that company not make that decision?
You just believe that 'politics' is outside the scope of the company. Other's believe that it is not.
