Whether they are voting shares or not is irrelevant as he is still invested in the company.
As long as he is still invested in Microsoft he is still invested in surveillance capitalism, the very thing he is arguing against, and I am sure if he wants higher dividend payments, he would want the stock to go up.
Even if they are voting shares, he has no realistic meaningful power or say when a shareholder vote happens.
If I hated the company I worked with for over 10 years why would I still have shares in the company, I wouldn't want anything to do with it, this includes selling shares and wanting Microsoft's share price to go down.
I understand your perspective. I imagine, since they're the shares he has and it would cost a lot of money to sell them all, this could be seen as another example of "No Ethical Consumption Under Capitalism".
Paying for food that Nestle makes supports their system too, for example.
