Also, Dell apologized and immediately fixed the issue, and didn't do it again. Lenovo never admitted it was a mistake, and did it again immediately afterward but in a more insidious way showing that they were sad they got caught, not that they did it. Dell's action was pretty obviously a mistake - it was sloppy, no effort was made to hide it, they fixed it as soon as they found out. Lenovo's was not a mistake - it was elegant, loads of effort was made to hide it (and to force it back on machines after it was removed), and instead of fixing it when found they worked to make it even harder to remove.
