I have been told many times in the last 20 years that the only thing that gets used comes from Microsoft. Literally the same shops end up with several piles of unmaintained crap which is either "not invented here" stuff, abandoned microsoft frameworks and all the staff have left to go find another job because it's not shiny any more.
Also a bad outcome.
A software development business is not really about programming languages, libraries, or tools, but about the game of power in the organization (even when the end user doesn't care how the product was developed). Anything that threatens that power is easily dismissed.
outsourcing that is just "kicking the can down the road" some poor developer is still left dealing with the same problem. It doesn't change anything other than who has to do the thing you don't want to / don't think is right.
