I'm sure there's worse hiding beneath the covers of some apps you use on a regular basis; e.g. Teams, Office, most AA/AAA games, etc. While Electron is far from optimal, just because a great app is built on top of it doesn't make that app any less great.

As an example, although I do have a prejudice against Electron based apps myself, that doesn't prevent me from using VSCode, which itself is based on Electron. VSCode is pretty great, and I'm not going to not use it simply because it uses Electron.
