I'm sorry but I am responding to this:
"believing that Glenn Greenwald should be thwarted is an opinion that, while obviously objectionable on HN, not actually unethical."
Are you trying to say that an employee for NSA contractor Palantir discussing targeting a journalist because of his work on a topic is separate from the employee's beliefs, therefore is not actually unethical?
How exactly did the journalist, or his career get brought up in a conversation between federal contractors about solicitation for work again? Was it to talk about of the reports they liked from him?
