Definitely it has become a selection criteria when picking tools. Electron? I don't care what a developer uses, nor how fun it was to use. I care about end results.

But to be fair. An Open Source project done in someone's free time for the love of it and shared freely in the wild as a humble contribution to humanity for the price tag of a Like in a forum, really should use whatever the author feels like using, as long as they don't treat it as a product and attempt to market it like it was done with care for anything but the developer's ergonomy. For what is worth, it could be made of Minecraft Redstone if the author feels like it, and nobody can judge them for it.
