I agree about it being a stretch, but we err towards indexing boundary cases. This one turns on whether you would consider the web application as being part of ChatGPT or not. In aviation, there are many systems that are part of safely flying from point to point that are not part of the plane itself. The control tower, the runway markings, and the processes built around these things. While the ChatGPT web application is not the model underlying the ChatGPT front end, it is part of the whole intelligent system.

Edit: On Slack we considering downgrading this one to the second tier status, which is an "issue," but our "issue" definition typically differentiates between events (a harm happened) and non-events (a harm may happen). This doesn't quite fit here. We have robust editor discussions around these ontological problems and are developing the ruleset in response to challenges. We aim for inter-rater reliability via the editor's guide. More details are here https://arxiv.org/abs/2211.10384
