I thought about asking this over here but didn't want to potentially derail the thread.

As a lay user, I honestly don't know what Electron is and couldn't tell you whether or not a particular app/program uses it. However, hanging out in techy spaces has helped me understand that people have some very strong opinions on it, often viscerally negative ones.

Think of this like an r/ELI5 thread: what is Electron, and why is it so polarizing? Many companies seem to be choosing it, so it seems like there's some major benefit to it, but many well-informed people, including lots of people in software development, seem to absolutely hate it. What's going on there?
