To my knowledge, at least in academia, Wolfram (Mathematica) seems to be used quite a bit by physicists. Also in some areas of mathematics it is used (but many mathematicians seems to prefer Maple). Concerning mathematical research, I want to mention that by now also some open-source (and often more specialized) CASs seem to have become more widespread, such as SageMath, SymPy, Macaulay2, GP/PARI or GAP.
I can't tell if you're saying that as if it's a good thing, or a bad thing.

Now, I really could've used something like this on macOS…
