I mostly agree with your point, but note that the author is male (well, the name is a commonly male one).
It's a bit telling that folks in the software industry[1] seem to assume that techies are male (a priori), but those who write articles of this kind are female.
Not blaming you for it, but it's something you should try to be conscious about and fix.

I had a female coworker by that name, so your assumption that I just assume that people who write articles like this are female and need to have my consciousness raised to "fix" my unconscious sexism is something you should try to be more conscious of and try to fix.
However, I clearly do need to question my assumption that since this was a female name before, it's a female name now, so I should change it to "he/she".
