The problem I see with most creatures is that the interaction with you may not harm them, but it may lead to their harm indirectly.
I grew up around in Montana. Lots of bears around where I was raised. Often people, mostly those not familiar with them, feed them. It's surely good intentioned, but generally it leads to the bears becoming more comfortable around humans as well as seeing them as a food source. Unfortunately this very often leads to the bears death. One summer the FWP trapped 2 (one in our back yard) and killed 1 more near my parents house because an out of stater had rented a home nearby for the summer and thought feeding the bears was being nice. (and by trap I mean cage, not foot trap, so they could release them a hundred miles away)
While I agree that petting a 10' shark isn't harming it, the shark may even like it (at bonneville sea base they have nurse sharks that like to be petted because they like the warmth) but if they end up losing fear of humans and swim up to another diver who doesn't act similarly, or then begin to go near swimmers, it may end in the death of the shark.
I'm not sure if a similar situation would occur with octopus, but I guess my point is that not every diver is as friendly as you and socializing with creatures may unintentionally lead to their harm even if they participate and you don't cause any harm directly.
