I see this from the reverse: while I strongly dislike that my day to day apps like Slack use Electron I couldn’t care less that Balana Etcher does. I use it every few months at most. It has features that the macOS Disk Utility does not so I still need it in my tool belt but if Electron allows Balana to make the thing more quickly and effectively then so be it. 140MB is not really notable to me in any way beyond irritating my OCD tendencies that know it could be smaller.

That said, I imagine I’d have a different opinion if I used Balana Etcher like I do Slack: a lot, every day. I imagine some sysadmins out there somewhere do. So I’m glad they have a non-Electron alternative.
