One important thing to note (according to the issuing letter I saw) was that this was a 10$ credit no strings attached. That actually makes me pretty happy to see it and I applaud them for it. Usually companies will try and attach a paltry sum like this to some thinly veiled settlement agreement to trick customers into surrendering their right to sue… in this case it was actually a gift - it may be a tiny gift, but it’s still a gesture of good faith before the lawyers get involved.
