literally no one will care, even the smallest Apple store gets far more revenue every day than you've spent in your entire lifetime buying Apple products.
Out of curiosity do you avoid all union shops or do you specifically have a bug against Apple. Do you refuse help from unionized EMS and Fire? Do you refuse to enter Costcos, Krogers, Safeways, CVSes, Macys, etc? Do you refuse to enter union constructed buildings? How about unionized restaurants? If you're in a city with unionized doormen and other labor groups (like NYC) do you refuse to enter those buildings? Do you not use meds that come from union pharma companies? etc
And I do wonder what you'll do as unionization spreads. With wages stagnant and inflation sky high unionization is definitely rising as a response.
