Halal food is laughably easy to come by in places like Jersey City and New York City, and everyday products such as Coca-cola are made to meet kosher standards during certain Jewish holidays:

(the special yellow cap, with the hebrew markings and the symbols, indicates that this 2-liter bottle of Coke is kosher)
Convincing a food company to provide versions of its products that meet certain dietary regimes is not in the least nefarious, and it would be foolish for any real business to ignore requests (or "pressure" if you like) because doing so would increase the number of customers who would buy its products, thereby increasing the company's revenues.
