Originally the problem started and both people who wanted to be legit and people who thought they would be banned started contacting support, worried. Adding fuel to the fire was a report that innocents were being banned, which was untrue (I don't doubt some went in the cheater pool).
I think the problem was originally support was saying report it because they didn't know what to do and wanted to know how wide-spread it was. So people were giving them the amount expecting the money to be removed, which R* didn't intend. They only wanted to research it.
So people called back and said, "why is the money still there?" Support quickly said that if they took some they would have to take all, but reassured they wouldn't be banned unless they were modding. So people realized they were stuck with it, but they knew they wouldn't be banned.
Then someone up top of R* (or a hacker for that matter) figured they could just create something that would remove the "gifted" money only. Which he was incorrect about, but being that so many people were concerned they viraled the story. As you could see, there was no other such comment since. People added in that the next update would be the cure, but nobody said that either.
R*'s solution was the hotfix. They got rid of the problem and washed their hands to move back to what they were doing. Unfortunately the rest of the world was reading into all this bad information and thinking update so they assumed some things they shouldn't have.
