For the most part I think it's irrelevant whether some bit of software is provided by Apple or a third party, I see weird hissy-fits about, say, the fact that keyboard customization on macOS uses Karabiner, and I just don't get it. Yes, none of the three+ package managers used on macOS are built in, why would anyone care about that, what possible difference could that make.

But work restrictions are one of the circumstances where the difference becomes a practical one, and getting your company to relax the restrictions may be infeasible, or more effort than it's worth.
