The point is: If you are using a unknown protocol, there is no one (who you
can trust) who can cross check if that tool is doing something bad.
For example. Skype protocol is still a secret. How can you tell they are not
abusig their user database? Ok they are big company now, but they started
very small and hungry and maybe there are still backdoors open.
If you publish a SIP soft phone that is doing dirty things, it is much more
likely that someone sits down and checks what this phone is actually
transporting out of your computer. Because he can do that.
The exposure on MS platforms is definitevely higher. But it does not mean
that the other platforms are more safe. AFAIK skype/yahoo & Co are available
not only for Windows.
