Right, but now there's this ambiguity about what counts as competing. And that ambiguity sounds like a risk to business, which opens a door to potential liabilities if CockroachLabs were ever to believe you are competing. That in turn makes CockroachDB a harder sell to management.
True. Though in this case it's very admirable how cleanly they have specified the exception case. But yes, it is a harder sell, and this is the main issue that these licenses must solve if they want to be successful.
