Now I have to find a new VoIP provider..
Skype was quite OK, but there is no way I will allow Farcebook to leech my contacts and to register who I talk to. Where Skype does a reasonable job, Zuckerberg's club has yet to understand the concept security and confidentiality and in this case it's about real money and credit card details (people having Skype subscriptions).
My credit card data and money in general is to stay as far away from Facebook if possible, so a merger will mean the search for a new provider.
