It’s the other way around. Lync, formerly Office Communicator, became Skype for Business which became Teams, not to be confused with Teams, a distinct, non-interoperable product made by the same company. Skype for Business probably took some code from Skype but I’d bet it was mostly about branding and it never had that much in common with the real Skype.

Microsoft killed Skype in 2017 and replaced it with a different thing also called Skype.
