An apology acknowledges wrong doing. Zuckerberg expressed sorrow about a thing that happened, then pats meta (himself) on the back for their “industry leading” moderation.

> I think it was a good enough apology. What was insufficient?

It's an expression of sympathy and a commitment to prevent future occurrences of whatever caused the suffering, using language approved by a legal team. It's an explicit non-apology, since an apology would be an admission of fault or wrongdoing.

A good apology includes taking responsibility for the negative outcomes you’ve caused as well as how you’ve made changes to ensure the harm doesn’t occur again. Here, you have the latter but not the former. He also didn’t explicitly apologize.

Does not take accountability, and uses passive terms so that they do not directly admit culpability.

"We measurably harmed you and are going to compensate you thusly"

His legal team will not allow that verbiage because it opens the door to basically infinite lawsuits

He does not take responsibility for what has happened. He only acknowledges an abstract problem.

[someone cheated on their partner]: Cheating is reprehensible and should not happen... [as opposed to, I'm sorry for having cheated and hurt you, etc...]

An apology contains phrases such as I'm sorry or my apologies.

He didn’t say “I’m sorry.”, for one.

An apology should be heartfelt while acknowledging responsibility and showing you’re taking real measures to not do it again. What he said was fumbling legalese and besides, I am not so sure Mr. Zuckerberg has a heart. You don’t get to his position in the world by having one.
