Not every developer runs a Macbook. Like many others for my laptop I use Linux running on a cheap ThinkPad with a quarter of the specs of the one you mentioned. ( I could afford to buy an overpriced Macbook, but I like my rugged $100 ThinkPad. )
As I stated elsewhere in this thread, vscode absolutely chews up my battery power. That's a practical concern. If I run several Electron apps on my laptop I'd be lucky to get an entire commute's worth of battery life out of it.
As someone who spent years complaining about the lack of cross-platform apps that I could run on Linux, I'm grateful everyday for Electron and for MS for using it for VS.Code.
The fact that it works the same on OSX and Linux is even better.
