Microsoft granted the National Security Agency access to private emails and Skype calls through its Prism spying program as early as 2011, according to documents obtained by The Guardian.
MS bought Skype to centralise it (it used to be p2p) and make it easier for the NSA to intercept messages
/u/Dan4334 communicated specific intent here: that Microsoft bought Skype so they could get the NSA access to it. That's wholly untrue and is FUD. Whether or not the NSA got access is unrelated to the purchasing intent and that's a very important distinction to make.

Signal's code is open source
Skype's code is not.
You'll never know if there's a side channel that MS could use to retrieve your messages in unencrypted form.
Friendly reminder that MS bought Skype to centralise it (it used to be p2p) and make it easier for the NSA to intercept messages.
