I don't think I have. I think this is a standard withdrawl tactic you use when people don't agree with your world view - which you view as self-evidently correct. As always, you've thrown in broadly irrelevant links.

Adults should make their own choices.

She chose to be in the tournament knowing her own mental health

She didn't fulfil her contractual obligations because of her mental health

She was fined for a code violation

She accepted her fine.

She opted out of the tournament

What you're saying is that they should've made allowances for her because she has mental health problems. You said they had a duty to do so as her employers - but she is a freelance contractor. Her job is to a) play tennis and b) talk about playing tennis. She did half the job well and then failed to show up to do the second half.

If people take the job whilst injured or whilst suffering from poor mental health that prevent them from achieving- they're adults and have made the choice to do so. If they suffer further injury or increased distress then they should pull out rather than no show. No show is a code violation.

Your ideal solution would be for her to be allowed to play tennis but not do the press obligations. This position is unfair on all other player in the competition as they're doing both parts of their contractual obligation. Yes, there's an argument to be made that the whole system can be overhauled - but that cannot be done MID tournament and certainly not by using mental health as a weapon to beat organisations with - buoyed up by the general shrieking of social media.
