Bad actors want to take advantage no matter what. It is the same case as Red Hat recent moves not to provide easy-to-rebrand linux distribution sources. Before they went the extra mile to foster collaboration, but were forced to be less friendly because of freeloaders.
Similar point here. Hashicorp have very good products that are open source as a way to foster collaboration. Freeloaders rebrand it and re-sell with no added value, so Hashicorp are forced to close it (or more like put a timer) to protect their investment.
As I said, I'm a big fan of open-source, and have been working on it for a long time, but am growing more and more frustrated with the current state of things, so much so, that it makes a lot of sense to me that companies that start with great collaboration spirit are forced to tighten their sources due to bad actors in the system.
