They all have millions of active users doing complex tasks in them every day! I's laughable that you expect me to take your vague complaints about Discord seriously not just as complaints but as dispositive signs that electron was a bad design choice.
Does this work on people usually?
Discord could have been a lack of resources as I previously said. They weren't a billion dollar company when the application was conceived.
Regardless the only thing keeping those millions of people at this point is lock-in. Even then people are actively looking for ways to move away from it. I'm witnessing the migration now and am looking forward to the day I don't have to hard restart the client 2-3 times a day.
