Personally in relation to people I think that they need the option of changing their minds. I think it is important to have a way back after making mistakes.
I’m inclined to be impressed by that old fashioned attitude to dealing with customers - the customer is always right. It has been rather depressing that some companies have been quick to tell customers that they are wrong maybe even evil and the custom of the evil is not wanted.
Basic respect and politeness for customers is important to me and I think that the email demonstrates that even though the advertising didn’t. So perhaps they will try a different approach. I’d give a second chance in this case.
