Windows yes, but Linux... no, at least if it's open source.

Closed source apps that compile fully static, these tend to be stable and Just Run in my experience... but open source apps? Good luck trying to bring these to even compile 10 years afterwards without going through an insane dance with Docker...

On Linux, there aren't 'apps' that normal people want. Basic things like 'functional 1080p/4k Netflix' and 'commercial software' aren't really a thing.
