That article is depressing. They nonchalantly attribute the behaviour to boredom and belittling the creature like a child: "Otto is constantly craving for attention and always comes up with new stunts so we have realised we will have to keep more careful eye on him".
Let's not attribute any aspect of his behaviour to the crippling reality of captivity. Oh, no.
There is no more evidence for your theory than theirs. Neither can be proven. So "let's not attribute any aspect of his behaviour" to anything is the only correct response.
That's a theory buddy. The word "speculated" might clue you in. Maybe that is the case. It is plausible. Maybe he is 'craving for attention and coming up with stunts'. Also plausible. Unless you're a fucking octopus mind reader, you can't say for sure. We have no evidence either way. Which is what I am trying to explain to developer2, who seems to think he can attribute the octopus' behaviour to the "crippling reality of captivity". He can't. And in fact, humans are notoriously bad at doing this with animal psychology, we tend to anthropomorphize them.
