This is a dangerous statement, although I don't think that was the author's intent:

> Before I get to other opinions, let me make clear that anything you can do to help you get a job is a good thing to do.

There are lots and lots of very evil things that will help you get a job, especially with companies that want to do evil things. Those are definitely not good things to do. I think the author intended a more restricted context like "any skill you can learn that will help you get a job is a good skill to learn from a technical perspective" (i.e., it might still be ethically wrong). This may seem pedantic but I've known some young graduates recently who went to work for very evil companies, and I think it's easy for impressionable minds to read statements like this and think "Yeah, see, everyone does it, who cares" without filling in the ethical background that the author assumes.
