Difference is a strength if it is different enough. That is, if devices are so different that building an exploit for one means it will not work on another. The problem they're trying to highlight here is that Androids may be similar enough for exploits to be widely applicable, while the absence of a centralized update channel that they control makes it hard to distribute fixes quickly. This arguably means that, in terms of security, they might be dealing with the drawbacks inherent in BOTH a monoculture and a diversified culture.
