A fair comment, but the argument I'd make against that is a lot of those creative tools are moving to the web. I personally work for Figma, and have seen that first hand. UI/UX design was entirely OSX/Windows centric for the last 40 years, and now it's platform agnostic. Even video editors are just at the nacent stage of looking at the web as an editor surface.
Totally hear you though for things like CNC milling software that's meant to stay static for the lifetime of the mill - that's not going anywhere.
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.
