I don't see why, if CyanogenMOD use is in fact rising. The rest of the title is about as sensational as the rest of the article, which is to be expected of an editorial.
"CyanogenMOD, the third-party, fully-open, bloatware-free port of Android, has recently passed a million installs."
I don't see it going that much further, and the number (which is obviously worldwide) is almost insignificant.
Hell, there are hardcore geek-oriented programming tools / frameworks etc that have had that many downloads or even more. For example, Eclipse Europa, a single release of the Eclipse Java IDE, had announced 2.8 million downloads.
So I see it more as a curiosity for hackers and tinkerers that is near its peak, than an actual platform that is on the rise and will have any impact on the market.
Even Linux never conquered the desktops of the great masses, and Linux has had even more benefits to it, especially being totally free as in beer to use, while with CyanogenMOD you still need to pay for your contract.
