This is a curious response. I would have used the same reasoning as an argument against Electron (or similar unified development systems): they are not consistent with all of the other native apps that people use.

I don't know if your reasoning is that looking like a web app means it is consistent with those apps, or that the apps look the same across platforms, but neither of those arguments are compelling to me. I chose the platform I am on because I think the interface is a good one that makes me more productive.

And I have never found an Electron app (or web app in general) that is as high quality as good native apps (on any platform). There are just so many compromises, and I am not even considering resource usage here. Everything just feels a little slip-shod.
