I mean, I feel like saying they said the phrase 'I am sorry' makes it true that it is an apology in the most literal sense, but it is sort of an asinine point, in my opinion. The comment you replied to was, from what I read into it, is saying the execs at unity didn't regret their choice, just that they were catching flak. They would absolutely have left the original policy change in place if it wasn't for the fact that it was going to tank their revenue. If they ever felt they could get away with this again at some point in the future, then they absolutely will try this again. It is a good victory for those who called them out, but they are not sorry that they tried and probably will try similar things in the future.
To me, it helps to think of corporate America as an abuser (because they are). Sure, the abuser can say I'm sorry again and again every time they harm you, but at what point is it not really an apology? If they keep trying (and often succeeding) in doing it, then at, some point, I think I wouldn't be satisfied with a hollow gesture.
I enjoy that I came in after the fact, and I too was confused like wallmenis, but got to instantly get further context. Don't know why, just gave me a small chuckle
