not quite.
https://news.ycombinator.com/item?id=30443310 people have taken it apart. the size comes from features you or I can call bloat, but my point stands. gmail is a lot more sophisticated than just an email client. Its pieces fit together in uncertain/mobile network conditions, with accessibility features, multi-media/web content support, spam detection, text prediction, multi-language support, syncing data across different google apps, within a fragmented ecology of devices and different input/display modalities.
The bundle size comparison doesn't tell a meaningful story. Were google to strip features they could get it down to a microscopic size, however this would make it a worse for the long tail of people who would use it.
It's not impossible to build a better debloated alternatives (look at figma) but it takes a lot more work than bitching and moaning
