To be fair, it appears to have hit 1.0 just hours ago, so this may just mean that OSI doesn't know about it yet.
OSI generally requires that the license steward/author submits the license for review if they want it to be approved.
Upon being asked about this by OSI President Simon Phipps, Kyle Mitchell responded that Blue Oak has no plans to seek approval (https://twitter.com/kemitchell/status/1104579340732264448). I would have found anything else surprising, given that last month Mitchell had this to say about the OSI (in the context of SSPL review):
> I've lost confidence in this body's ability to make rigorous decisions, or even facilitate focused debate, […]. So I've otherwise stopped responding, and focused my efforts where collective time and talent have hope of yielding practical results.

Read the license. Read what others say about it. Read about the law. Apply your mind.
