It would seem, from reading the story, that this was a professor who did not actually do the leg work to be a professor. Namely, providing students with more than just written resources and giving exams. Why pay a prestigious do-nothing professor a salary when you can just offer an online course that has the same level of engagement?
I'm speculating that areas with undersea cables are often marked as "no anchor" zones due to the risk of damage (in areas where such practices are followed).
So the drop in damage from anchors and extended motor boat presence might eventually outweigh the initial damage from laying the cable.
"Getting lost in your knowledge management system is a fantastic way to avoid creating things. Or calling that friend you’re estranged from. Or doing anything else even mildly threatening. It’s also a fantastic way to convince yourself that unpreparedness is what’s between you and creative work. If you believe you’re unprepared, know that you will never transmute into the perfectly prepared person that you think exists in the future."
