No, it's definitely a win for Linux. I get it. I've dabbled in software minimalism. I love native dev. I know the web "sucks." But the range of mainstream software available for Linux has exploded now that software is moving to the web (including Electron) and I can't see how that's a bad thing from the perspective of a Linux user. Of course I'd rather open a web browser to run an app than change my entire operating system to run an app.
By using non-free software, you're compromising on politics that don't really affect anything directly - not unless great many others suddenly embrace the ideas behind Free Software.
The compromise of using SaaS in the cloud in lieu of regular, native software, is affecting both you and society directly.
