I have the strong urge to point out it’s the other way around; Adobe and Autodesk have to support Linux. You’re of course right though, with the strong lock-in effect from those big companies it’s almost impossible to switch unless done on company-level. And even then project partners will expect files to be in a specific (proprietary) format most of the time.

It was really disheartening to see Ondsel ES fail, it was a valiant attempt at creating a business-grade Open-Source CAD solution based on FreeCAD. Unfortunately Autodesk’s monopoly extinguished any attempt at finding funding, despite existing interest by those who actually use that stuff (I assume Autodesk is fucking expensive like any monopoly software…). Education, Production, Distribution… those few big companies own and control literally every part. It would probably take both governmental effort as well as some kind of soft UI-standardisation to crack these power structures.
