A REFRESHER ON THE HARM OF PORK INGREDIENTS
* Pork Tapeworm: http://en.wikipedia.org/wiki/Taenia_solium
Taenia solium, also called the pork tapeworm, is a cyclophyllid cestode in the family Taeniidae. It infects pigs and humans in Asia, Africa, South America, parts of Southern Europe, and pockets of North America. Like all cyclophyllid cestodes, T. solium has four suckers on its scolex ("head"). T. solium also has two rows of hooks.
* Pork tapeworm infection: http://www.medterms.com/script/main/art.asp?articlekey=18494
Pork tapeworm infection: Known medically as cysticercosis, an infection caused by Taenia solium (the pork tapeworm). Infection occurs when the tapeworm larvae enter the body and form cysticerci (SIS-tuh-sir-KEY) (cysts). When cysticerci are found in the brain, the condition is called neurocysticercosis (NEW-row SIS-tuh-sir-KO-sis).
1. Muslim countries, it is found only very rarely, due to religious dietary restrictions.
2. signs and symptoms of the disease depend on the location and number of cysticerci in the body.
3. ticerci in the muscles: Cysticerci in the muscles generally do not cause symptoms. However, you may be able to feel lumps under your skin.
4. ticerci in the eyes: Although rare, cysticerci may float in the eye and cause blurry or disturbed vision. Infection in the eyes may cause swelling or detachment of the retina.
5. ticerci in the brain or spinal cord (neurocysticercosis): Symptoms of neurocysticercosis depend upon where and how many cysticerci (often called lesions) are found in the brain. Seizures, and headaches are the most common symptoms. However, confusion, lack of attention to people and surroundings, difficulty with balance, swelling of the brain (called hydrocephalus) may also occur. Death can occur suddenly with heavy infections.
Yes, it is inconvenient to have to rule out several more store bought foods. But since when was anything good or worthwhile in life easy? It is related in al-Bukhari and Muslim that the Prophet, sallallahu aleihi wa sallam, said: "The value of [one's] deeds is determined by [one's] intentions; and thus for each shall be according to his intentions." Yes, this religion has been made easy for us. But that is no excuse to do whatever we want. That means we are to pick the easy path when faced with two or more HALAL choices.

LOOKING AT THE INGREDIENTS LABEL ON THE BOX
If a label on food from the USA says LECITHIN, this is various oils from animals including pork. If, however, the label says SOY LECITHIN, this is the oils from soy and okay. Look on your labels. If it a box from the usa and it says GELATIN or LECITHIN, do not eat it. Well, unless you don't care about those pig tapeworm and other garbage from the pig possibly entering your body. Or maybe you think Allah will just "understand" that it's okay because of the inconvenience of having a diet different from the majority. In Muslim countries, they usually do not use the pork oils when creating gelatin and so they are usually ok to eat. You don't have to use pork oil to create gelatin.
Ideally, one would contact the food manufacturers to determine the ingredients for all the processed food we tend to eat. Or, baring time constraints, one would rely on the Muslim organizations that have already done the research for us. Creating food called "gelatin", which isn't the same as something becoming salt over a long natural process, is simply a cooking process.
Why would we want even a drop of pork or the oils from pork ..... in our food? It's not like we're starving or there is no alternative.

APPLYING THE RULING CORRECTLY
From the article in question, it says, "The ruling is upon what the object is, and not what it was."
Yes, that is correct. It is food with pig as one of the ingredients when cooking. It is therefore not halal.

CONCLUSION
While someone may want to chide others for "making halal into haram," it should be noted that there are other valid differences of opinion in which one of the opinions is that something is halal and the other opinion is that something is haram. So, just picking the side of "halal" doesn't always make a person to be on the right side of an issue. One could equally argue that making something haram into halal is a form of oppression, as it physically can harm the body and can anger Allah if done. However, we would get nowhere.
We simply have to just discuss the point, which is whether or not cooking food (resulting in a chemical change) makes something haram into halal. If that were true, then we could just cook pure pork meat and because it goes through a chemical change, we would then believe it is ok to eat.
Please don't over-complicate a very simple directive. It's really quite simple: don't ever eat a food that you believe contains or may contain pork.
Allah is our Protector.
