My take is that they're related because a being's ability to experience sentience, and especially suffering are ethical grounds to not breed them and inflict unnecessary suffering through harsh captivity and slaughter.
Its not possible for me to tell if thats been your stance on everything like farming chickens and salmon, or if you were one of the people that just found out Octopus' are smart and made a line there, or another group or individual with a unique opinion
there are some observations and personal dietary choices I can be sympathetic towards, I just don't know which one I'm hearing at the time and when it comes to Octopus or the animal-of-the-month I find people not being able to articulate their new opinion at all, but being shocked that the listener (me) isn't automatically on board or making a line at sentience.
What do you eat?
I eat many things, but nothing from animals :)
