alt Hacker News> selectively adhering to the letter of the law
Are you suggesting that companies should violate the law here? What do you recommend?
Edit: charitably, "adhering to the letter of the law" is sometimes shortened to "law-abiding" and is generally what we want.
You've misunderstood the point.
Prior to the beginning of your excerpt is the word "You", meaning the comment's author is the subject, not "companies". I'm saying the commenter is appealing to black letter law for the answer to the question "what happens when..." but we have observational evidence to answer the question.
