I don't think MIRI has any reason to take you up on this offer, as responding in this way would elevate the status of your writings. High status entities do not need to respond specifically to low status entities, and when they do, it will be obliquely and non-specifically addressed to the broader class which contains the specific low-status entity. Additionally, it would look mean-spirited to try to 'kick someone while their down', especially as this post in some ways resembles a call for a truce. As such, it would be a mistake for MIRI to accept your offer, even before taking into account the resources that would be required. If I was MIRI I would totally ignore this.

Given this, either you have failed to understand what apologizing actually consists in, or are still (perhaps subconsciously) trying to undermine MIRI. At the moment all you offer is the implication that you would continue your disruption were it not for the toll it has taken on your health. Contrition would demand at least a genuine apology - something like "I am sorry for acting badly" - if not actively working to undo the harm you have done.

Fortunately, I think you overestimate the impact you had. Probably your biggest effect was wasting everyone's time.
