I think you're conflating the issue of gender neutrality with more recent discussions of non-binary and trans gender identities. People have always needed gender neutral pronouns to say things like "Everyone has their flaws", or to talk about individuals whose gender is unknown or irrelevant. The only question has been whether it's 'he/him/his' or 'they/them/theirs'. If you speak a dialect of English where 'they' can function as a gender-neutral singular pronoun, then there's really no reason at all not to use that pronoun to refer to Steve Wozniak.

The use of singular 'they' has been common for (at least) several decades, long before any substantial number of people were worried about trans issues.
