I've been out of the loop for awhile to be honest and haven't taken time to read any "new" guidelines/rules so I apologize for not following them.
Electron applications get a lot of negative feedback across the internet I've noticed. I actually have less respect for wire now that I know they use Electron. Wire is a great messaging tool but..Electron? Was it the easy way out for them?
I think Electron is just extremely hyped. They fetch huge prebuilt binaries from the internet while building.
