My whole point is that what people pay for changes over time. So, if you invest in a piece of software, then it's very likely going to continue evolving to stay profitable and chase whatever new fads happen to be.
This has been the case with literally every piece of commercial software I've ever used. And a lot of the time the changes either have absolutely no value for me, or they're actually detrimental to my workflow.
And clearly I'm not alone, because every time a major version change happens with popular commercial products a lot of users will complain about it. However, they have no power to do anything since they just have to follow whatever the current trend is, or find a new piece of software to use.
It's also a false dichotomy to claim that software is either commercial or open source. There are plenty of companies making money from open source products. This is a good combination since it provides commercial funding for the project, but also ensures that the users can always fork it if it and move it in a different direction from the original developers.
I also disagree that open source applications are in any ways horrible. GIMP and Libre Office are both excellent piece of software that work perfectly fine. I use GIMP all the time, and I have much easier time getting around it than Photoshop.
Also, would like to hear more about what specifically needs to be fixed on Linux. For example, what deficiencies does Elementary OS have compared to Windows?
