I hate when someone on Twitter gets something wrong and then instead of deleting it they reply with "sorry I was wrong". Due to the way Twitter works very few people will see the reply, deleting is the only way to really make things right.
They should have a “retraction” feature. Go to the Tweet, it shows the original Tweet, but with a “This tweet has been retracted by its author” notice on it.
Deleting it could be interpreted as covering up one’s mistake. “Retraction” would be owning it, and in a more immediately visible way than doing so in a reply
a) The context was helpful
b) They deleted it
