all attorneys represent their clients; your attorney does not have to share your opinion of the law or public policy, they can still interpret what the law means to you.
if you are afraid your attorney might have a bias (they are human) you may get better advice from the "misaligned" POV: the flaws/holes in a privacy law found by a pro-business conservative attorney are more likely to find sympathy in the courts from both fellow conservatives and progressive judges.
It's not hard to see how this enables an institution to gate itself from criticism.
