The article was about people using tdcs for durations and at levels of current that haven't been tested, measured, and documented, and then claiming that it has a known, beneficial effect, while implying that there are no negative side-effects.

When scientists study these effects, they study them over groups of people. For some individuals, it hurts where it should help. For others, they get a larger-than-average boost. At the same time, research seems to suggest that some abilities are increased while others decrease, for a given protocol.

It's not pseudoscience that a lot of people are trying a new, untested thing. It's pseudoscience if they claim benefits based on subjective perception or claim that the same protocol will help everyone, without documenting objective, replicable proof.
