Neither npm nor NuGet are volunteer driven organizations. npm is owned by Github, NuGet is owned by Microsoft, and I'm sure that there are dozens of other examples behind many key pieces of free dev&ops infrastructure that are owned by for-profit companies.

Are they allowed to do it? Of course! Are we allowed them to call them out on their bait & switch tactics? Of course, what else are we supposed to do?

Just because something is common, like building a user base based on implicit promises and then pulling the rug once the service reaches critical mass, doesn't mean it should be accepted and normalized.
