The answer is that developers mainly use Macs, and they don't want to deal with a crappy Electron application in daily use so they give themselves the privilege of a better experience even if it makes no business sense.

You can see the same with Telegram, which has first party Electron applications for Windows / macOS / Linux, a first party native macOS application, and a bunch of third party blessings including a Windows UWP application.

Note that there needs be an environment for this. You don't see a native version of VSCode or 1Password 8 because those orgs actually care about their applications and take great effort to make them feel good despite being built on Electron.
