The author is fighting a strawman. Rather than engage with the specific problems these solutions were built to solve they dismissively regard them as just flavor of the week trends purely for the sake of chasing newness. This is true of the entire post, but I'll tackle just one since it's emblematic of my issues with all the rest:
The argument for Electron and React Native isn't "it's modern", it's "it's much cheaper". Hiring experienced desktop application devs to build a quality native app for each platform is going to be expensive, hiring a few JS bootcampers to build one react UI that works on every platform is extremely cheap - shittier performance is the tradeoff to instantly have access to every platform. It's not a coincidence that Electron apps like e.g. Slack, Spotify, Discord are massively dominant players in their markets, I doubt you'd look the engineering leads of these companies in the face and tell them that you believe they put no thought into the tradeoffs of Electron and that they're just following trends.
