All else being equal I do prefer the F/LOSS alternative - and even pay extra for it - but I am not against paying for an obviously-superior proprietary alternative. The real question has always been "Do the F/LOSS alternatives to this proprietary Windows-only software suck badly enough that dual-booting the nightmare that is Windows is the lesser evil?", and in a lot of cases my conclusion has been that the preferred option is to... not use any version.
To give a concrete example: FreeCAD is basically unusable, and Fusion 360 is the obviously-superior proprietary alternative which doesn't run on Linux. Do I want to design my own 3D-printable parts badly enough to deal with Windows so that I can use Fusion 360? Ehhh, I think I'll just stick to mostly printing ready-made assemblies I download off the internet. Would I pay €10 / month for a hobbyists Linux version of Fusion 360 (which is free for Windows and macOS)? Heck yeah, zero doubt!
