If you find the writer’s “no capital letters” writing style obnoxious and difficult to read like I do, you can paste the text into this: https://www.textfixer.com/tools/capitalize-sentences.php

Edit: And now that I’ve read it, I can’t say I understand exactly what the author’s point was. To say “free software” is “dead” and to say “free software has a specific goal and I don’t care about it” are two different things and seems needlessly dramatic. The rest of it is a long-winded description of the state of open-source licensed software and how corporations use it, often in an exploitative way. It may be a long acknowledgement that you are not going to solve the worlds problems with software alone, which is worth remembering.

corporations have little to nothing to lose by publishing existing source code

That is SO wrong lmao, imagine if SAP or Microsoft open-sourced their ERP solutions, or if Intel released their microcode source, or any other bif corp releasing their 20+ year work.

I agree that for big project, plain open-source got more popular than free software, but I wouldn’t say FOSS is dead. In the Linux community, it seems to be somewhat alive, pretty sure it is as well in other communities.
