RIP HipChat, last top tier native work chat program. We were paying customers for HipChat and were forced off when Atlassian killed it. Replaced by stride/slack/discord/teams all built on electron and all with awful non-native UI and web app like performance.
I know why they do it: electron is cheap and easy to spam on every platform. I don't know why: people pay for this crap.
Perhaps the issue is that people don't pay for it? Teams is free, bundled with other MS stuff that people are buying anyways. Discord is free. Slack is mostly free (until you are already stuck with it).
