> strong experiences that users love

Oh my god, that sounds so cringey, right out of a marketing copy. It’s hard to wrap my head around someone writing this with a straight face.

Ah yes, the classic attacking of the author instead of engaging in a debate on substance

> If they were so "terrible" and "out of place" users would reject them, and they don't.

You are acting like users have a choice. For example: Microsoft Teams is an abomination of an app. It's slow, clunky, eats memory like there is no tomorrow and feels totally out of place on macOS. Still it's a huge commercial succes and I use it every day, even though as a user I absolutely hate it. I simply have to use it because my employer chose it as the company collaboration tool. And they didn't choose it because of it's incredible UX, they chose it because we already have an Office365 subscription and it was included in that, so we already paid for it anyway.

Some Electron apps have been huge commercial successes despite their terrible UX.

You are certainly entitled to feel that way about Teams and these kinds of apps. My point is that's just your opinion and doesn't necessarily reflect the majority of the users of those products. I can just as easily say that I love the UX of Spotify/Slack/Discord/etc and don't care at all that they don't use platform UI controls to render most of the app.
