I believe they changed the game to fix 2 problems. The problem of cheap farming, exploit the game and they will eventually fix it and the fact that fireteams couldn't reap the benefits of destroying the supplies together. It's not lying if they don't mention the farming fix. Most likely they didn't because they didn't want to offend players by insinuating that they did something wrong. The community already treat Bungie like they killed someone's dog and made them eat it. People who aren't mature enough to handle all the information shouldn't get all of it.
