I find this silly. The guy didn’t own the network. He had little vested interest in it’s security. Why did he care if it was hacked through no fault of his own? Let it burn.
Pride in your work.
Anyone who likes working with computers takes considerable pride in the machines they build and maintain.
We just got back from buying a replacement power supply after my husband’s unexpectedly failed. Got the replacement from the same shop we got the original case and board from, and the lady who runs it grinned from ear to ear when we told her how happy we were with that machine they built for us.
Same for this guy...he built it, and he wanted to ensure it was treated carefully, not bungled by incompetents. His name was on it, thus his reputation.
