The open letter to Microsoft said: "It was a shitty move to not update the client for three years, which resulted in this, mostly. It was annoying that you ignored almost every tweet to @SkypeSupport about issues with Skype for Linux. But it is absolutely disgraceful that you dropped the Linux client BEFORE any alternatives are available and without telling your users."
The campaign invites people to tweet their support with the hashtag #thanksbill which, unless we're missing something, suggests that their frustration stems from 2008 when Bill Gates last held a full-time position at Microsoft.
The full tweet reads: "@SkypeSupport dropped support for Skype for Linux, we can no longer accept calls. Support us by sharing: http://nickforall.nl/skype/ #ThanksBill CLICK TO TWEET."
Problems with outgoing calls began on 22 February but the campaign organisers, 'Boltgolt' and 'NickforallNL', believe that it is indicative of a long-term decline for the Linux client.
"We do understand that Linux is a competitor of Microsoft's Windows. But we do not understand why this results in a lack of support for Skype," continued the letter.
"Linux is actively being used by power users who cannot or do not want to use Windows because of a lack of features, and now those ($kype for business and private purposes) are dropped by Skype."
Nothing could be further from the truth, on the other hand, for users of other Microsoft 'rivals', Android and iOS, who are seeing what we lovingly refer to as John Hurt chest burster apps as the company tries to become a cross-platform bundle of love and friendship.
So what's going on with Skype for Linux? We've asked Microsoft and the firm hasn't got back to us. Plus ça change. µ
It's time for our regular two-step through the Google news
