In my mind, no apology is better than a 'sorry you were upset' non-apology, but there are apologies that manage to seem genuine as well. As I write this I am reminded of the show 'The Orville's "apology tour"... I don't necessarily think an apology is needed or helpful.
Always interested in examples of corporate PR, whether negative, neutral-ish, or positive.
Edit: obviously I don't care enough(?) about the specifics of this instance... Hopefully it's also obvious that I appreciate the chance to evaluate the community's response to a favored company. Mozilla seems to be allowed quite a bit of leeway.
