Can't this logic be spread to a bunch of other injustices in the world? If I interact with some party who is contributing some injustice to a group of people, whether in terms of work conditions, lack of political voice and so forth does that mean I'm collaborating/supporting their regime?

An example is the current situations happening in Hong Kong and Uyghur. And the fact that everything we buy on a day to day basis is "supporting" this oppression.
