Yea, usually devs make tradeoffs for reasons. Sure, maybe a dev didn't know that Electron was so memory heavy/etc, but often it's a well known fact. They had their reasons for choosing it, you're free to use something else or implement an alternative for them to maybe fork/etc.

Why should someone use a language/framework/etc they dislike just to make something in their spare time and FOSS?

Don't get me wrong, I think Electron is a problem - but I don't blame people for choosing it. Often our FOSS development aspirations are limited by time, energy and shockingly enjoyment.

I can choose to use what I want, and you can choose to not use it.

Disclaimer: I've never used Electron, but I'm shocked it's not blatantly obvious why people would choose it.
