I don't like such statements either. Choosing the web as an application platform is legitimate from my perspective, but instead of building electron apps, it is better to build progressive web apps (PWA). However, there are some use-cases when some specific technology for building it as a PWA is unavailable and therefore, building it with Electron might be the best alternative. But as a result, the author shouldn't just state that you are the problem ('... not the target audience'), but instead, state his reasons for choosing that technology (e.g. why he is using Electron instead of building a PWA).
