This feels like a breach of information ethics. You're presenting information to another party without a key detail that could potentially undermine your case, simply because you feel you have the moral high ground and the detail shouldn't be there in the first place.
The author believes "it is the law and they should comply with it," except for a certain element of the fine print which the author thinks is too lenient. It makes me a bit uncomfortable whenever someone openly justifies using omission as a tactic.
