Several years ago, in response to a request that Apple commit to only agree to measures that wouldn't impact the bottom line, Tim Cook told an activist investor "If you want me to do things only for ROI reasons, you should get out of this stock." (It was in response to a question about Apple's environmental stance, but Tim likened it to a request to ignore accessibility issues.)
If I disagree with Paypal's disagreement, I'm free to withdraw my investment and go to a company that will ignore social issues.
