A whole lot of words follow but if fucking Spotify is on your list of free software, all that indicates to me is that you’ve put a whole lot of work into failing to understand the concept of free software.
That’s a bit harsh. I would agree with you that they seem to be pretty ignorant of the finer points of free software, like the difference between free-as-in-beer software, free-as-in-freedom software, and so-called “open source” software. But to be fair, the article was more about economics than about software, and I mostly agreed with a number of their arguments.
