On a more serious note; keeping ants in captivity is not natural, so the argument that the living insects have no route of escape does not make sense to me, as we are already in an unnatural environment to begin with.
As for the argument that the feeder insects will take a long time to die: yes. Insects take a much longer time to cease bodily function and it's fairly hard to tell when an insect is dead and not just bodily movements based upon left over synapses firing. For all we know, they could still be alive after we "kill" them ourselves to then drop into the formicaria. Who is to say us squishing, stabbing, tearing, etc. prior to feeding is more humane than giving an insect to our colonies to kill.
We can also argue that it is beneficial to give our colonies (the mature ones that can handle it) live arthropod feeders as it permits our ants to use their natural abilities to hunt something and not have bored foragers standing still in the outworld, unable to explore and forage.
Feeding live prey to snakes being bad is not widely frowned upon in the hobby and mainly a minority. That is a single .com opinion and does not represent a majority in the hobby. Anecdotally, I have never seen reptile owners say it's inhumane to feed live to their animals at the several massive shows I've been to, the hundreds of people I've met, and stores I frequent for supplies. Yes, there is a chance that your animal could be harmed in a live feeding and that is a risk. However, it does not often happen when your animal has normal instincts to subdue its prey. It's also the responsibility of the owner to monitor their animals during feeding and make sure no injuries to their pets occur.
Regarding the possible introduction of mites from a living insect. I don't see how this is relevant since mites can be introduced through a plethora of ways, or even just show up on their own. Dead insects can also carry mites just the same.
Continuing the topic on nociception and your interpretation that the flies experience "pain" as more developed organisms do— that just sounds like any living thing trying to avoid things that can cause harm to the body and protect already damaged portions of oneself. This is a logical thing to do for most organisms and not necessarily what we consider to be "pain." Insects have been proven to be able to learn to avoid certain substances, such as pesticides, so they don't ingest or get hurt by some other means. Again, this doesn't necessarily mean they're experiencing "pain" on the scale we do. I started reading the full journal article, not just the magazine writing you linked. I will finish it at some point and if I remember, come back and share my interpretation.
While your opinion is not inherently wrong and you are allowed to have it, this feels like you are trying to push your moral opinion upon the community when there is not enough scientific research done to even prove your point. I am going to continue to not care about how insects are fed to insects as based on the evidence gathered so far throughout history: insects are incapable of conceiving "pain" like we do due to the simplicity of their nervous system compared to ours. There is also nothing wrong at all with how you choose to feed your colonies. I personally pre-kill crickets and larger insects prior to giving them to a colony because it makes it easier for the ants to take down since I don't really keep colonies to huge mature numbers, not because it's immoral to feed live. The feeder is still twitching and moving around slightly most of the time anyways. Like I said above, insects take a while to die and who knows if it's really more humane to incapacitate one before feeding it off.
A problem us humans often have is putting human traits as such onto things that are not human. I do not believe this thread will lead to anyone changing their own feelings on the matter as it has come up before in the past and has always never come to a conclusion.
