This is a common criticism of teacher unions in the USA [0]. They donate dues money to left-leaning political causes against the wishes of many of their members. In a union shop, dues-paying employees have no choice in the matter. It is compelled political speech.

I expect this will be a big issue in tech unions also.

Union shop, not closed shop. Closed shops have been illegal for over 70 years.

You are correct, I used the wrong term. I have fixed it in my original comment.

In the US, outside of states with right-to-work laws, a union shop can still require workers to pay dues even if they aren't members of the union.
