You make it sound simple, but it’s not.
If you operate a SAAS company, and ICE approaches you to buy your service, you suspect it might be used in the family separation program. If you say: “I’m not doing politics!” and decide to sell them the service, you are being complacent in the policy that ICE enforces, and therefor just did some (highly questionable) politics. If you deny them, you also did (morally correct) politics.
If your workers use open source software and ask if they can contribute back upstream, but you deny them on grounds of intellectual property, you just did politics. The same if you allow them. If you pay your workers above market rate, allow them to unionize, have a liberal vacation policy, or force them to work on-site, you are doing politics. Albeit on a more personal scale then in the previous example.
If most of the other offices in your downtown building where your startup resides put a BLM flag in their window, but you opt not to, you just made a political decision. If an employee puts a prominent Palestinian flag on their desk, and you ask them to take that down, you do so on a political basis.
I hope you get the point. Businesses simply don’t have the option of not doing politics. The power dynamics involved simply prevent that from being a possibility. “Not doing politics” is more often then not simply an excuse for doing highly questionable politics.
