You are correct, there is no strong indication of active suicide.

However, it certainly put him into a state of mind of neglect, not caring anymore and not taking care of himself and most importantly, no way out. The words "I cannot play chess anymore without doubt of being accused of cheating, no matter what I do" are haunting to me. At that point he had multiple cameras targeting all screens he had and everything he could see, and it wasn't enough to Kramnik.

At such a point, it feels like arguing semantics.
