That is your personal opinion, which you are entitled to and I will not argue or judge it. But that is not the moral of the story since not everyone shares your opinion. Even the government does not view general “porn” by itself as “nefarious and immoral.”
If you read the post carefully, he did not get into trouble for having/viewing porn, he got into trouble for “viewing it on the government network.” You could theoretically get into the exact same trouble for uploading and watching an anti-porn, religious PSA on a government network without proper authorization.
