I believe reducing loss of privacy to only financial costs is the wrong approach. How will you quantify this cost when, for example, Drata runs some fancy ML algorithm on the gathered data, and starts offering employers a "unionization risk" score for new hires that they have intel on? What do you do when being without an evaluation by some spy company like Drata, since you're so privacy conscious, itself becomes a black mark for employers?

Rights should not be thought of in terms of their financial cost.
