I feel like Linux alternatives often falter by trying to offer as extensive of a feature set as the proprietary options. GIMP would be better if it simplified it's menu's and focused on offering a strong central feature set, then expand on that core over time to offer a powerful workflow of it's own.
I noticed this especially with FreeCAD, which is trying to do like 12 things for some reason? Just offer intuitive parametric cad and focus on it. We don't need OpenSCAD inside FreeCAD because OpenSCAD is already it's own thing for example.
