If aluminum is perfectly safe why do they have to line the cans? There has to be a reason to separate the food with the can right? Companies would not spend extra money to apply the liner if it made no difference.
Something as acidic as soda, left in the cans for months, can leech flavors from the aluminum. This does not mean that short term, low acid contact will leech enough to taste.
I think enough people just didn't like the taste. Some people still don't like to drink from cans, even if they are lined.
