Agreed, but Matt is not the innocent and distressed open source maintainer who hit a breaking point, he's the extremely wealthy CEO of a company that brings in hundreds of millions a year in revenue. The CEO who recently tried to extort another large company for tens of millions of dollars per year to be directed to his personal for-profit company.
The problem with Open Source as a movement isn't just the megacorps using it, it's also that paying for the project's ongoing development stopped being the goal for many monetization efforts—making the shareholders or the maintainers themselves (or in this case both) wealthy (or in this case even more wealthy) has become the new goal.
That is why it's such a problem that these companies don't "give back". Having the software in the world doing its job is no longer the primary goal of starting an open source project, and the "takers" are encroaching on the founders' market cap.
