Someone doing harm to you doesn't automatically mean you wish harm to them. Not that I necessarily take what Garry says at face value but it's definitely possible to unironically take this viewpoint.
It seems like an accurate paraphrase in the context of other known news about Delve, and it was shorter than "We trusted them to not do something intentionally fraudulent and then lie to us, and I believe they knowingly violated that trust by doing something intentionally fraudulent and lying to us."
