It's a Prisoners's Dilemma. Since apps are evaluated in an isolated fashion there is an incentive to use all the resources available to appear as performant as possible. There is further incentive to be as feature-rich as possible to appeal to the biggest audience reachable.

That this is detrimental to the overall outcome is not unfortunate.

There's not extra apparent performance in using Electron. A truly more performant solution will be still more performant under load from other applications.

The extra performance is on the side of the developers of the app. They can use a technology they already know (the web stack) instead of learning a new one (e.g Rust) or hiring somebody that knows it.
