I don't like it but I can't entirely argue with their logic. I once had a short argument with a friend who wrote "I will put the photo's up later". I chastised her for her inappropriate use of an apostrophe but she said that she considers it to be a contraction of "photographs" and therefore the apostrophe replaces "graph". I didn't like her explanation any more than I like the food company's but I still can't say that they are 100% wrong.
