This "apology" is about as vague as can be. If you actually wished to be accountable, you would be a lot more forthcoming about what happened, exactly which internal processes are the problem and why, and address the fact that the lack of proper data exfiltration was used here as a club to beat hundreds of thousands of dollars out of a nonprofit and longtime client.

I already only use Slack when required, and I have several philosophical issues with your platform, but this is a nail in the coffin for many of us here. I will certainly never recommend Slack and will use this situation and your vague apology as the reason.
