Not wanting to wake the sleeping dogs? I think our few 100 devices still work with Skype because we are not important enough a group to use the kill switch on.
The strenght of Skype (besides now compromised encryption) used to be for many years that no mater the version of your Skype client you could still establish voice calls and text chats.

Since Microsoft took over devices became unsupported. Skype clients needed to be updated to latest versions including bloatware and advertisements.

Skype should have been protected under some telecom law for the public interest.
If governemnts had a vision about the future of telecom, we could be talking to big wall mounted displays or projections in every room like in SF movies and call those conversations private.

That is clearly not what we want.

Now using Wire.com, Swiss based, Encrypted, Open source, Elegant multiplatorm client.. but it is a tech demo and probably just a matter of time till some Google buys it including all my data.
So I am not advertising it like it was 2003.
