The source of most of complaining about Electron and companies/developers choosing to use it is that it's not just an ordinary trade-off. The gains - being cross-platform - accrue mostly to the producer side (cheaper to develop and maintain). The costs - resource use at runtime - happens entirely on the consumer side.

In other words, it's a typical case of costs being externalized, making the supposed trade-off be a "free win" instead. Since software resists commoditization, consumers don't even have a way to pass those costs back onto the vendor (by e.g. leaving for a competitor).
