> Over time Signal developed an Electron-based client that annoyed me every time I use it. It requires relinking to the phone, it can't decrypt messages read from mobile, it can't send messages, it can send them, but the other party can't read them.

While I agree the app is a resource hog for what it is, I haven't ever had to relink my phone after the first time unless I reinstalled the app or got a new phone (duh). As for unreadable messages, I use Signal daily and have never had that issue once. I have had that issue multiple times using Whatsapp however.
