Yea, having a first mover advantage on every major product in and around the language is how they profit. Sort of a pretty old racket actually. Create a brand new market vertical, and then build the ecosystem for it before anyone can even access it. It's kind of like pre-mining a crypto currency. Except that in this case it's actually useful and a primary way for the field to move forward, indeed many of the most useful languages in the world start like this.
