When they said native, they actually just meant local.
./Electron.app
Is any more local than: php ./MyApp.phar
Especially considering the former spins up an entire browser + PHP server instance, while the latter runs the code directly.What's more native? Running a Python app that uses PyQT, or running a single purpose web browser in a window that calls a sandboxed+bundled Python server and renders HTML widgets?
In addition, OP was talking about locality. In both of the aforementioned examples, they're equally localized (both executing on the machine they're loaded on).
