Her personal motivations make total sense and this isn’t a judgment of her, but your comment makes it sound a little like misaligned incentives just switched places, but the misaligned research incentives remain (and she doesn’t do research professionally anymore) and now she introduced a new misalignment: the content creation business.

It’s totally fair that emotionally she was done with one and able better to continue work with the other, but removing the hobby element actually did remove one set of well aligned incentives and did not replace them with another.
