I agree. Like others here I don't know the context, so maybe I don't know what I'm talking about, but her first paragraph seems about as sincere and direct an apology as anyone could reasonably want.
After that she talks about broader organizational stuff which isn't intended to take away from her own apology ("Separate from this personal misstep...").
It's a shame that based on the reactions in the linked thread, many seem unable to take what seems like a genuine apology at face value
