A lot of people only used the Adobe site to watch videos like Adobe TV. I purchased Lightroom 4 from Amazon for example but had a simple password to go on the Adobe forums and Adobe TV. I couldn't give a monkeys if a hacker got my password as there was no Credit card to go with it and nothing for a hacker to gain. Ask yourself how many log ins had current card details or any at all ? The software code that was stolen is more of a problem for Adobe.
And no my password was none of the above
