I get the sentiment, but the examples are bad. There is no "magical bar" that decides whether you have ADHD or not and it always needs to be cross checked with the wellbeing of the actual person. And much of the article is about bashing psychology which... I do resonate with, but I'd rather have more substance rather than reading accusations alone.

I know people with actual ADHD and some medication has helped them to function again and endure social exposure and even enjoy it. That doesn't change my impression that a vast amount of people see to identify with ADHD because it's currently a trend (remember the time when everybody thought they had OCD?).

Other than that, the field of psychology is constantly evolving.
