I disagree with this Not-Made-In-Here mentality Oldschool keeps bringing up, especially in education. It is like refusing to use Java to teach computer science because you are worried about students only being able to program in Java afterward.
There is nothing wrong with teaching concepts using industry-standard tools. So long as you actually learn about what those tools do under the hood, you don't have to worry about being locked into proprietary tools.
Just because I learned how to do some complex engineering computations in MATLAB doesn't mean I can't figure out how to do the same thing in something like Python, since I know the math I want those tools to do.
All those people who get locked into those tools probably never learned what they do or how they work. This is why universities should teach the concept behind those tools, so students can figure out alternative solutions when those tools become unavailable.
