I don’t know if this is correct, but it’s interesting. The Register quotes from a Microsoft technical note that uses “she” to refer to actions by a potential hacker, and adds this comment:

All right, I’m only going to say this once: ‘He’ is the singular indefinite pronoun in English (“if a person drinks too much, he will likely experience a hangover”). ‘He’ also happens to be the masculine personal pronoun.

‘She’ is the singular pronoun of personification in English (“if England fails to advance America’s foreign-policy ambitions, she will suffer terrible consequences”). ‘She’ also happens to be the feminine personal pronoun.

Confusing the two exhibits not a warm-and-fuzzy concern for the inclusion of women so much as a writer’s or speaker’s ignorance. Using the feminine personal pronoun as an indefinite article is as moronic as using the masculine personal pronoun for personification. Thus the captain greets us: “Welcome to my ship. Isn’t he splendid?”

Give it up, people. It’s not thoughtful; it’s just illiterate.
