You're missing the point entirely. If Cisco doesn't play well with an app, what do you do? You buy other hardware. You'd be hard pressed to find a company with more monopoly powers in the IT industry than Microsoft. They have it, and they love leveraging it to "encourage" us to adopt their new offerings by forcing users into closed standards of which they have sole control. DirectX is a good example and their legal woes over bundling IE are also well-documented. I think another one in the making is the 'Games for Windows' iniatiative as it implements Live features to tie in with the 360 and inexorably herds people into subscriptions.
