I agree with most of this. However, I might take issue with the motivation you ascribe to professors: "only car[ing] about increasing the number of academics who studied in their lab." Another explanation, one that I find myself feeling sometimes, is simply mismatched incentives. Practicing academics and students headed to industry simply have different incentives, and that can add friction to the relationship.

I think it would be helpful and useful for departments to consider other ways to facilitate industry pathways that don't so heavily rely on the advisor.
