This is the key thing, right here.

Although Veganism is a laudable choice, especially considering how meat production contributes so disproportionately to climate change and ecosystem destruction, it is a personal choice and not a fundamental dietary restriction that limits what you can actually safely eat. While an employer should make reasonable allowances to allow you to meet your own personal restrictions, meals in the bush, well away from infrastructure, makes any such allowance that much more onerous for an employer to meet.

Don’t get me wrong, tho - I am not a corporatist. Nothing would have made me happier than the company being found at fault and getting nailed to the wall. Corporations will try to get away with everything they legally can, and a lot that they legally cannot, so long as no-one complains. But the legal ruling did follow the law, and the law was very clear.
