Neither did I! And I'm a bit humored to see other people pronounced it like that too :) I wonder what causes it, regional dialect or something? I'm part-Mexican, grew up bilingual and it just sort of happened without thinking about it, I discovered 'warez', immediately pronounced it "Juarez" (without the Spanish jota inflection) and it took 30 years (today) to learn it's 'wares'.
I used to hear both pretty regularly, talking to BBS folks back in the day. Thankfully, nobody really seemed to fight about it like the pronunciation of "GIF"...
