Probably someone like me who's old but still keen to learn.
Or someone who's trying for self taught
For these "student" offerings, only the appearance of credentialism matters. They've never cared about self-taught, at least from all the evidence I've seen.
The reality is it’s a company giving offerings away for free. Do the people in these companies who care about education wish _everyone_ who needed to learn could have it for free? Of course. But welcome to businesses. The definition of “student” is as it is because it’s a verifiable segment. Self learners are, unfortunately, not.
