That’s awesome, but keep in mind that the AppData thing is likely a feature and not a bug.
Think about it another way: if they install in AppData, they can likely bypass IT depts and other business bureaucracies and get a foothold somewhere in an organization. It’s absolutely malicious, both in terms of tech and business practices, but it works.
That might have been true a long time ago, but nowadays Windows makes it easy to black/whitelist executables from the home directory with stuff like AppLocker. Meanwhile, the MSIX subsystem lets users install apps safely without needing admin access into c:\Program Files.
So, what Electron does might have been a neat growth hack once, but now it's as likely to hit roadblocks as not (at least on any modern Windows network with a switched-on IT department).
