Love the attitude, but the concepts are a bit wonky.
There's Free as in freedom (usually referred to with the Latin word “libre”), and Free as in free beer. Open source is just the ability to read and contribute to the source code. Not all open source is free, but libre (freedom) software has to be open source.
That's why it is usually referred as FLOSS, Free and Libre Open Source Software.
There's a myriad of licenses, not just GPL, and GPL is not the only FLOSS license.
There are source available software projects, that do not adhere to liberty principles. There's also free software (as in free beer), that is not open source or even source available.
Blender is open source and also free software, and also libre software. Because Blender is FLOSS. This, however, does not prevent some specific forms of enshittyfication. It's just that forking the base source code is always a possibility.
Edit: Ok, forget the love attitude part. You just called two men who have a disability and are some of the corner stones of the free software movement “corporate lickspittle”. Wow, you have to be an ignorant piece of shit to call the man who conceived the ‘bazaar’ thesis that defines FLOSS a lickspittle, an utter idiot to call a man who hates proprietary software a corporate lickspittle. Bruce Perens and Eric Raymond may not be saints, no person is perfect. But you are just dismissing and insulting people who are the reason you can exist with a modicum of freedom on the internet space.
