I realize that Linux desktop is a marginal OS, deployed on only 2% or so of desktop/laptop computers, and that so long as the energy in Linux desktop is devoted to developing endless distros rather than focused on developing better GUI applications, that is unlikely to change. But many Windows 10 users also use Linux desktop (most for work-related reasons, others just for recreation) and deploying Edge Chromium as a Windows/Linux/Android cross-platform browser would increase Edge Chromium's market share, it seems to me, and better align Edge Chromium with Microsoft's move toward open source and Linux support.
