Things people get wrong about Electron

Electron's choices, especially the very idea of building interfaces with web tech and shipping large parts of Chromium to render them, are not uncontroversial. Reasonable people wonder why we made those choices. Operating systems already have user interface libraries. In those libraries is usually also some kind of WebView, often actually based on Blink (Windows) or WebKit (macOS, many Linux distributions). Why go through all that trouble of bundling parts of Chromium? And, even if we go through that trouble, why do so many apps (Visual Studio Code, Slack, Discord, Figma, ChatGPT, Claude, Notion, 1Password, Docker Desktop, and many more) go along with it?.
