The interesting part of it is that those applications are mostly written by GNU/Linux developers, thus decreasing the likelihood of GNU/Linux ever becoming a relevant desktop in world wide market share.
What's wrong with Electron apps?
They're slow, bloated and not native anywhere.
There's plenty of programs which are native to the environment they work in which are also slow and bloated.
But there are plenty that aren't, which can't be said for electron. I'll avoid the bloated ones regardless of the tech.
The only well-written Electron app I'm aware of is VSCode.
Everything else is slow, memory hungry, and insanely bloated.
