If it was anything other than a blanket "don't do this," maybe. It's also like a crowd of new software engineers being told on day one, "By the way, you probably know this, but don't hack the payroll server to boost your paycheck." It's something the average person would never seriously consider, but in the event someone is boneheaded enough to actually do it, it negates the "I didn't know I couldn't" excuse. You can feel insulted if you want, but it's not a message _personally directed at you_, it's a general warning that, because of a few extreme incidents, needs to be explicitly stated out loud.
