Ignoring the open-source vs free software discussions that are bound to come about from this well said. Large companies exploiting developers and abuse towards the maintainers is probably my biggest bugbear when it comes to this.

In fact I have a similar post https://boyter.org/posts/the-three-f-s-of-open-source/ which I redirect people towards if they become aggressive towards me when I am trying to help them. Thankfully I have only had to use it a handful of times.
