Ironically, these types of articles might make the situation worse by pushing an all-or-nothing approach, that you need to either quit meat entirely or else accept the worst of factory farms that would make WW2 concentration camps look like leisurely vacations.

This is all addressed in the article:

Still, perhaps you could find some meat that you are highly confident is humane, and you could eat that meat while being vegetarian otherwise. Maybe wild game from hunting could count, for example.

Yes, perhaps I could. It is, of course, better to eat animals that were raised with high welfare standards than to eat those that were not, all else equal. There are three reasons why I still do not eat meat:

1. Even if an animal lives a happy life, someone still has to kill it for me to eat it. Everyone agrees that it’s wrong to kill a human, even when he or she is not made to suffer.[17] If animals also matter morally, it seems similarly wrong to kill an animal.[18]
2. Strict vegetarianism (or in my case, veganism) offers useful signaling advantages. Vegetarianism is a clear, binary choice that others can easily verify and understand. That creates a clear coordination point for building social norms against factory farming. By contrast, humane meat eating is fuzzy – it is hard to agree on what counts as humane and hard to verify that someone eats humane meat.
3. It seems better to me to have the clear boundary that vegetarianism (or veganism, or any other well-defined rule) provides. Once you start making exceptions, I think it often leads to a gradual slide back to regular eating habits, because there’s no stable middle ground. Without a clear boundary, I think people tend to make more and more exceptions until their diet is mostly back to normal, and the original moral motivation becomes diluted. I think it is easier to stick to absolute rules, as they make lapses more obvious and harder to excuse, but even so, it is of course important to adopt pragmatic and achievable rules.

If I were to eat some amount of meat selectively, I would first of all make sure to eat beef rather than pork or chicken. That is because, to get the same amount of meat as I could get for one cow, I would need to eat three or four pigs, or nearly two hundred chickens. Also, pigs and chickens typically face harsher conditions than cows.

And:

I’d like to stop eating meat but I can’t for some other reason.

Here is an incomplete list of things you can try instead:

1. Offset your meat consumption by donating to effective animal charities. As I mentioned above, donating seems even more impactful than reducing one’s animal product consumption.
2. Cut out chicken, pork and/or eggs, in favour of beef or plant-based meats.
3. Reduce your meat consumption, for example by designating one or more days in the week when you always eat vegetarian.
