Their propaganda^W PR fluff about the weight of gold recycled from iPhones has a line that triggered my bullshit alarm: "2204 lbs of gold" [1]. This has been regurgitated by news media[2] as "more than 2204 lbs of gold" without them doing any more fact-checking.
1000 kg is 2204.62262[...] lbs. For them to put the exact number "2204" smells like someone told them "about 1000kg of gold" and whoever wrote that report just converted that to "2204 lbs". And since it's a rounding down, they can claim "More than 2204 lbs". Apple not knowing how significant figures work and giving out a number that was probably a guess to be an exact figure? That's why the alarm I mentioned above got triggered.
