I was quite surprised by the title, but once I understood it’s about corporate open-source products, it makes a lot more sense :)
These companies are relicensing projects to cover for the fact that they are ignorant of how to run a successful business.
That’s a pretty restrained point-of-view, even more so when comparing small businesses open-source projects and what a trillion-dollar company could do with the same source code.
From what I remember, the FSF has nothing against selling your product, it’s the source code which has to be available.
In other words, you can sell a free software, yet users can pool together the resources to buy your product and install it multiple times, or they can even just get the source and compile it, and even redistribute it
