and
"(Privileged) are more likely to reinforce their privilege (because the don't see their privilege and/or want to keep it)"
are two different things.
At face value these to things look the same, but upon examination it's only a convenient simplification.
The fact is, regardless of how you paint it, you're making prejudiced assumptions about him/her based the fact that (s)he belongs to the group of "people who write 'he' when talking about coders of unknown gender".
Assuming that (s)he is "privileged" is just yet another prejudice, not a fact upon which to base your opinion.

Men are more privileged than women, that is fact.
"Never attribute to malice that which is adequately explained by stupidity."
- As an aside, while I firmly believe that both genders have equal _potentials_, I think that due to various socioeconomic and cultural pressures, genders are _not_ equal at everything in execution, on average. It might take a while for that to happen.
In my experience I've found people who assume genders to have a reason for assuming. The most common reason is they don't believe women can program as well as men.
