Doesn't surprise me either.
Society is becoming increasingly lax about use of traditionally vulgar language.
To be fair, the use of vulgar language was traditionally looked down upon when it was used in the presence of a lady - as this passage from Trollope demonstrates:
That she-Beelzebub hates him ..." said the archdeacon, permitting himself to use very strong language in his allusion to the bishop's wife. It must be recorded on his behalf that he used the phrase in the presence only of the gentlemen of the party. I think he might have whispered the word into the ear of his confidential friend old Lady Lufton, and perhaps have given no offence; but he would not have ventured to use such words aloud in the presence of ladies.
As Civ V is a computer game, perhaps Firaxis is assuming that no ladies will read the manual?
