So you're saying there are projects where I cannot use Qt? The fact is, there exists projects that do not have the option of using Qt without paying for expensive licensing. Such projects should at least consider using Electron which might have significant non-technical advantages for them.
It is cool that what many consider to be the best commercial desktop GUI is also open source, I will admit that much. Still, we shouldn't complain too much when many projects choose to use Electron, it's licensing is just so much more permissive which is a significant advantage for many projects.
