There is no substitute for Revit on Linux. Autodesk won’t even bring it to MacOS, which is what many architects prefer. People have been asking them for years to develop for other operating systems and they don’t give a shit. The person you responded to wasn’t blaming anyone for autodesk not supporting Linux. They were answering the question of why they still use it. I use Revit every day for work and I would wipe windows from my work pc in a second if there were an alternative. I’m working on a $300m project right now where it specifically states in the contract that we must use Revit so until autodesk decides to support it or goes fully browser based, we are screwed.
You can still dual boot or use virtual machines in your private devices. It’s the usual workaround for people who are forced to use one particular incompatible app. That fact is literally not what’s stopping you from using Linux. It’s only stopping from using Revit on Linux, but again, that’s not on Linux, there’s nothing any of us can do, take your grievances with Autodesk. This fact doesn’t forbids you nor does it prevent you from using Linux for everything else.
That still doesn’t stop you from using Linux or macos on your private devices. I’m also forced to use awful software at work but that’s I call a fraction of my salary pain money (Schmerzensgeld). That’s fine. If it is enough I’m willing to deal with Microsoft, Autodesk and the like. But in my personal life. I have the choice and I would never use it if I don’t like it.
