Makes you wonder about some of Microsoft's undisclosed intentions when Yahoo! was a suitor[1] given what happened when/after Skype[2] entered Microsoft's fold. Though the credible timeline[3] given suggests that Yahoo! may have already been forced to capitulate.
If you're going to bash Microsoft, at least find an accurate point to build your case on. Skype was added to the PRISM program 8 months before being acquired by Microsoft in 2011, and was looking into how to cooperate with wiretaps since 2008 under Project Chess.
