I don't like the tone of the headline demonizing Electron. I think if you flip it you have the incredible headline of "Electron allowed Microsoft to grow to 250M users for Teams", which paints the IMHO correct light into how Electron has played the role of growing Teams from 0 to where it is now. And only now that it has proven tremendous success, and to extract more of juice on performance for lower-end devices, it's being switched to a custom-built engine by investing massive resources into it. So Electron has served its purpose greatly in here IMHO.
