No, they're saying they are going to be "more open", which implies they were already open.

No apology there (nor should there be).

Though it means they were not open "enough". I agree on no apology part, it is just an "open" statement.

It's an admission that the world is changing and they have to keep up.

wtf, "guilty of not being open". Not being open is a crime now? It's a perfectly valid business strategy.

it's an admission they think they should've been

So adapting to change is now "an admission"?
