Just look, for instance, at FPGAs: almost all the tooling is proprietary, very expensive, and very buggy too. Or look at PCB design: Altium seems to be the standard here still, despite Kicad having made huge advances and by most accounts being as good or even better. It took decades (Kicad started in 1992) for the FOSS alternatives here to really catch on much, and only really because PCBs became cheap enough for hobbyists to design and construct their own (mainly because of Chinese PCB companies), and because CERN contributed some resources.
I'm not sure what the deal is with engineers hating collaboratively-developed and freely-available software, but it's a real thing in my experience. It's like someone told them that FOSS is "socialism" and they just reflexively dismiss or hate it.
Apple and NVIDIA are using Allegro (or customized versions thereof.)

KiCad is faster, absolutely not better.

Vivado is free for a great number of devices (not just the "lite" version, either, depending on the board - U50, U55, etc.)
No open source tooling can even remotely compare in ASIC implementation flow or FPGA implementation.
That seems like a matter of taste. We switched from Altium to KiCad and I very much prefer it. We don't do any RF stuff, so there might be things that don't quite work in KiCad, but for what we do - power electronics - it works perfectly well.
