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.
I've spent a lot of time at this point with both toolkits. I use the open source tooling extensively for my own designs. But you tell some grizzled RTL person there's no power analyzer or native SDC support or that UTM was only recently supported in some simulator, and they're going to laugh at you. They've been doing that stuff for 20 years. I know this because I've done it several times (though other people find particular things, like free RTL verification tools, much appreciated.)
I think FOSS/software people paint some very rose-tinted picture in their mind where the mere availability of something for $0 would make it an obvious choice, even at only 10% of the functionality. But that's not how people see it in reality. Many people, including engineers, think of it the other way: if it's so good, why is it $0 and how do I know it will keep being developed? They've made their peace with the fact that the $5000 tool will exist practically for as long as they need, get the job done, and be supported.
