What you're thinking of is product lock-in, not segmentation.

Besides, many superior solutions exist and have for a long time: TeamSpeak, Ventrilo, Mumble. Skype is laggy, buggy, and high memory overhead, without mentioning the DDOS risk (exposes IP).

Thanks for the correction.

Truthfully I would not consider TeamSpeak, Ventrillo, or Mumble as a superior solution. The benefit of Skype has always been that it dod not require joining more than one server. In the article example, consider the line about individuals having their Yahoo username on their badge.
