I encourage you to read my argument from the top again. I speak in terms of probabilities, not absolutes. I don't disagree that many people might not notice performance degradation when running multiple Electron apps. However, it is an incontrovertible fact that (all other things being equal) an Electron app will consume more memory than a native app will; and some people will experience swapping and reduced performance when running Electron apps where they might not experience that if they were solely running native apps instead. Also, it's important to keep in mind that people often run a healthy mix of apps at once--both native and Electron--and they'd have the ability to run more of them without risking swapping if they ran fewer Electron apps (again, all other things being equal). The closer you get to exhaustion, the more economy of consumption really matters.

I just can't see how this is that controversial a claim.
