Nokia was on the path to obsolescence before Microsoft purchased the failing company. Nokia lost more than $3 billion dollars in 2012. You don't spend billions of dollars to purchase a failing company and then intentionally fail some more. Skype works the same as it always has for me and I pay them nothing. Are you upset that Skype hasn't moved forward at all? That seems like a valid criticism but hardly "evil".
The stuff they did in the 90's was true evil. They actively sabotaged competitive technology and companies. Making agreements in bad faith was part of their corporate culture. They considered open source a cancer they were trying to snuff out.
