What do you mean? Adam Silver wrote a statement supporting Morey's right to free speech, and then doubled down on it after receiving flak for his free speech support.
"We support free speech" is a cop-out, because China is happy for you to support free speech, as long as you don't say anything they don't like. It would be a stronger stance to say, "Actually, we think Morey was right", especially if it's going to cost them money to do so.

Really I don't know what more you're expecting. This is a strong stance.
