Let's continue drafting Section 4, Paragraph 2:* On the other hand, proprietary CAD vendors face a potential disruption to their licensing models. Autodesk has long maintained a dominant market position by controlling the DWG format and licensing its official translation technologies to third parties. If open-source or lower-cost alternatives can reliably convert complex 3D data without their proprietary software, the economic incentive to maintain expensive
