That is probably true, when you live in a society where you probably still want some money for your work.

The greater implications of that might have something to do with how we get articles like "Software below the poverty line": https://staltz.com/software-below-the-poverty-line.html

Or maybe the revelations about how "well" supported the people who maintained Log4j were from the open source community: https://words.filippo.io/professional-maintainers/

  Earlier this week, a severe RCE in a logging library called Log4j2 got everyone, from Apple to Minecraft. As of yesterday, the maintainer who patched the vulnerability had three sponsors on GitHub: Michael, Glenn, and Matt.

That's why it's hard to be angry with companies and people trying to get paid for their work, supported by various software licenses in one way or another. I do still mostly support open source in spirit, though doing that with my wallet on OpenCollective (or GitHub Sponsors or whatever) is also a good thing to do.

No one needs to get angry at anything, and people are free to change their minds if they decide their previous decision to open source was a mistake. It's just worth remembering that this is a deliberate part of choosing to make open source software, and not an unintended consequence.
