Spotify doesn't use Electron, though. Also, I do not expect Apple to care about Electron because delivering shitty electron experience only benefit their native apps.
If anything the ones that got a worse reputation here is Apple itself. The bug basically slow the whole system, not just the application that has the bad behavior.
Sure, people in Hacker News now know that the issue is "that Electron bug", but I am sure lots of other people that are less tech savvy just kept questioning what the hell is happening and maybe even considered an upgrade. But maybe that is the whole point.
Seems like the right patch is to just crash any app attempting to use the private API so blame would go where it is deserved. And if it caused a lot of more awareness of the need to get rid of Electron, bonus.
